|---|---|---|---|---|---|
| show | These depressions are found in both of the maxillary bones and the mandible. They are functionally important as the teeth are cemented into these depressions.
🗑
|
||||
| anterior triangle of the neck | show 🗑
|
||||
| arytenoid cartilages | show 🗑
|
||||
| bone collagen | show 🗑
|
||||
| show | These are the live portion of the tooth. They are capable of repairing the tooth when it is damaged. They require a blood supply to stay alive.
🗑
|
||||
| cementum | show 🗑
|
||||
| clavicle | show 🗑
|
||||
| show | This is a cat muscle that corresponds to the superior division of the human counterpart. This muscle elevates and retracts (adducts) the scapula. It is served by the spinal accessory nerve. It inserts on the clavicle.
🗑
|
||||
| show | This muscle combines with the sternomastoid muscle in humans, but in cats it remains separate. It is at least partially covered by the clavotrapezius of the cat.
🗑
|
||||
| show | Normally branches of the brachiocephalic artery. Humans: the right vessel is a branch of the brachiocephalic artery, the left is a branch of the aorta. Found in the carotid sheath on each side with the vagosympathetic trunk and the internal jugular vein.
🗑
|
||||
| show | This vessel is a medial branch of the common carotid artery. It serves the cranial end of the larynx.
🗑
|
||||
| show | This artery is the first medial branch of the common carotid artery that we will study in the cat. It serves the thyroid gland.
🗑
|
||||
| show | This cartilage of the larynx is the only cartilage that forms a complete ring. It is narrow anteriorly and wide posteriorly. It is connected superiorly to the thyroid cartilage and inferiorly to the trachea. It forms most of posterior wall of the larynx.
🗑
|
||||
| show | The exposed part of a healthy tooth. A thin layer of enamel (2-2.5 mm) covers it. Under the enamel is dentin. In the center of the tooth is the pulp cavity filled with pulp. This part of the tooth meets the root at the neck close to the gingiva (gum).
🗑
|
||||
| dentin | show 🗑
|
||||
| digastric muscle | show 🗑
|
||||
| enamel | show 🗑
|
||||
| show | The superior most of the laryngeal cartilages. It projects superiorly and attaches to the tongue. Functionally it is important in humans because during swallowing it covers the opening of the larynx when the larynx moves superiorly.
🗑
|
||||
| esophagus | show 🗑
|
||||
| Eustachian (pharyngotympanic or auditory) tube | show 🗑
|
||||
| show | This is the name for an organ that produces secretions that pass through a duct (except for one-celled goblet cells). The secretions pass into a cavity or onto the surface of the body.
🗑
|
||||
| external carotid artery | show 🗑
|
||||
| show | It emerges from the deep side of the neck muscles and runs caudally to meet the subclavian vein on the same side in the cat. This union forms the brachiocephalic vein on each side. This vein receives blood from the head region except the cranial cavity.
🗑
|
||||
| external maxillary artery | show 🗑
|
||||
| external nares | show 🗑
|
||||
| show | Its both motor and sensory. It has parasympathetic functions controlling the lacrimal gland, as well as the mandibular and sublingual salivary glands. It exits from the skull via the stylomastoid foramen. Both branches bracket the masseter muscle.
🗑
|
||||
| show | In nursery school we called this the gum. Importance: Forms a seal around the neck of the tooth that keeps food and bacteria away from the surface of the root where there is no enamel and the dentin would be exposed and susceptible to the decay process.
🗑
|
||||
| glossopharyngeal (IX) | show 🗑
|
||||
| show | This is the name for the opening between the vocal cords that leads into the trachea.
🗑
|
||||
| show | This structure is the bony portion of the roof of the oral cavity. It is formed anteriorly by the palatine processes of the two maxillary bones and posteriorly by the horizontal plates of the two palatine bones.
🗑
|
||||

|
||||
| show | This cranial nerve is a motor nerve that serves the muscles of the tongue. It runs with the sublingual artery.
🗑
|
||||
| internal carotid artery | show 🗑
|
||||
| show | This vessel is part of the carotid sheath, which also includes the common carotid artery and the vagosympathetic trunk. It usually joins the external jugular vein before the junction with the subclavian vein.
🗑
|
||||
| internal nares | show 🗑
|
||||
| laryngopharynx | show 🗑
|
||||
| show | This structure is made up of four major cartilages and houses the vocal cords. Functionally it is important because it connects the pharynx with the trachea, as well as being the structure where sound is produced. It extends between C4 and C6.
🗑
|
||||
| mandible | show 🗑
|
||||
| mandibular nerve (V3) | show 🗑
|
||||
| show | Lies deep to the mandibular body anterior to the angle of the mandible in humans. Its duct opens lateral to the frenulum of the tongue. Its secretions are controlled by the facial nerve (VII).
🗑
|
||||
| show | This muscle, which is the prime elevator (closer) of the mandible, originates on the inferior margin of the zygomatic arch. It inserts on the mandible. In the cat it is partly covered by the parotid salivary gland.
🗑
|
||||
| show | Part of the temporal bone. It is the insertion for the sternocleidomastoid muscle. Several other muscles that you will not be responsible for also attach to this landmark. As a group these muscles are responsible for rotation or extension of the head.
🗑
|
||||
| maxillary bone | show 🗑
|
||||
| maxillary nerve (V2) | show 🗑
|
||||
| mouth | show 🗑
|
||||
| show | This vessel is a lateral branch of the common carotid artery. It leaves the common carotid close to the cranial thyroid artery and supplies blood to the muscles of the cervical region.
🗑
|
||||
| nasal septum | show 🗑
|
||||
| show | This space is the superior/posterior division of the pharynx. Normally air passes through this space on its way to or from the trachea. The pharyngeal and tubal tonsils are found in this space, as well as the eustachian tube of the middle ear.
🗑
|
||||
| show | This space is the superior/anterior division of the pharynx. It is posterior to the oral cavity and extends from the soft palate to the epiglottis. Both food and air pass through this space. There are two tonsils in this space.
🗑
|
||||
| show | These nerves form one of the two functional subdivisions of the autonomic nervous system. They are responsible for the 'feed or breed' response. These nerves are responsible for preparing the body for digestion and gestation.
🗑
|
||||
| show | This gland is the largest of the salivary glands. It lies superficial to the masseter muscle. As with most glands, it has a rough texture. It is an exocrine gland. Its secretions are controlled by the glossopharyngeal nerve (XII).
🗑
|
||||
| show | This structure is primarily connective tissue and it surrounds the root of the tooth. The cementum actually secures the tooth to this structure and this holds the tooth in its alveolus. It is continuous with the periosteum that surrounds the bone.
🗑
|
||||
| show | Primarily a fibrous connective tissue membrane that surrounds all bones, except at the articular surfaces. Produces/removes bone tissue from the surface of the bone, and increases diameter of bones as they grow longer. Has nerves and blood supply.
🗑
|
||||
| perpendicular plate of the ethmoid bone | show 🗑
|
||||
| show | The sternocleidomastoid muscle, trapezius, and clavicle in humans define this area. In the cat there is no sternocleidomastoid muscle, rather the cleidomastoid muscle defines it.
🗑
|
||||
| show | Located in the pulp cavity.Because the tooth is alive, the vessels are necessary to provide nutrients and remove cellular wastes. The nerves are sensitive to both pressure and temperature changes. Named for a famous religious leader that lives in Rome.
🗑
|
||||
| show | This is the space within the crown and root of the tooth that is occupied by the pulp.
🗑
|
||||
| root | show 🗑
|
||||
| show | This is the narrow part of the pulp cavity that is primarily within the root of the tooth. It is occupied by the pulp.
🗑
|
||||
| show | An exocrine secretion. It contains water, electrolytes, mucus, and salivary amylase (ptyalin). It moistens the mouth, helps control bacteria (mucus and enzymes), helps regulate the mouth's pH to be about 7.2, helps lubricate the food. aka spit.
🗑
|
||||
| show | This enzyme is found in saliva. It converts starch into disaccharides
🗑
|
||||
| soft palate | show 🗑
|
||||
| show | It controls muscles that attach to the skull and the scapula. It controls the sternocleidomastoid muscle and the trapezius muscle. It is also unusual because it leaves the cranium by way of the foramen magnum and the jugular foramen.
🗑
|
||||
| sternocleidomastoid muscle | show 🗑
|
||||
| show | This muscle originates on the sternum and inserts on the hyoid bone. It depresses the larynx and mandible.
🗑
|
||||
| sternomastoid muscle | show 🗑
|
||||
| subclavian artery and vein | show 🗑
|
||||
| show | This vessel is a medial branch of the external carotid artery. It runs with the hypoglossal nerve along the medial margin of the digastric muscle. Functionally it is important because it supplies the tongue with blood.
🗑
|
||||
| show | In the cat this structure is situated deep to the submaxillary duct and the digastric muscle. It has its own ducts that open ventral to the tongue. Its secretions are controlled by the facial nerve (VII).
🗑
|
||||
