Bones in the body
| Question | Answer |
|---|---|
| axial skeleton consists of | head, back, and chest |
| appendicular skeleton consists of | pectoral girdle, pelvic girdle upper extremity and lower extremity |
| The frontal, temporal, parietal, occipital, ethmoid and sphenoid are bones in the______________ | skull (cranium) |
| The 6 bones in the face are: | mandibular, zygomatic, lacrimal, nasal, palatine, and inferior nasal conchae |
| The 3 bones in the ear are: | malleus, incus, and stapes |
| The hyoid bone is a u-shaped ________bone in the neck to which the tongue and other muscles are attached | free-floating |
| vetebral column consists of: | cervical (neck), thoracis, lumba, sacrum (back of pelvis), and coccyx |
| Thorax consists of: | sternum and 21 pairs of ribs |
| The appendicular skeleton consists of: | pectoral girdle, upper extremities, pelvic girdle, lower extremities |
| pectoral girdle | clavicle, scapula |
| upper extremities | humerous, ulna, and radius; wrist (carpals): scaphoid, lutate, triquetrum, pisiform, trapazium, trapezoid, capitate, and humate; metacarpals (5) and phalanges (14) |
| pelvic girdle (os coxa): | |
| lower extremity: | femur patella (knee cap), tibia, and fibula, ankle (tarsals):navicular talus, calcaneus, cuneiforms (3), and cuboid; and metatarsals (5), phalanges (14) |
| bone markings | fossa, sinus, foramen, projections for muscle attachment |
| fossa | depression (acetabulum, glenoid |
| sinus | cavity in a bone lined with mucous membranes (maxilla, sphenoid, ethmoid, frontal) |
| foramen (window) | opening through a bone, as the foramen magnum in the occipital bone for passgae of the spinal cord |
| projections for muscle attachment | trocanter on the femus, crest of the tibia, and spinous process on the vertebrae |
| movements of joints | abduction, adduction, flexion, extension, inversion, eversion, supination, pronation, circumduction, dorsiflexion, planterflexion |
| abduction | move away from the midline |
| adduction | move toward the midline |
| flexion | bending, decreases the angle between articulating bones |
| extension | straightening; increases the angle between articulating bones |
| inversion | turning in |
| eversion | turning out |
| supination | palm up; supine: face up |
| pronation | palm down; prone face down |
| circumduction | moving the distal end of an extremity to make a circle |
| dorsiflexion | toes pointed up |
| planterflexion | toes pointed down |
| bursa | sac filled with fluid designed to prevent frictionat a joint |
| ligaments | tough connective tissue that secures bone to bone |
| tendon | tough connective tissue that connects muscle to bone |
