Question | Answer |
---|---|
Consists of collagen and elastin fibers in soft, gel-like matrix | Areolar Tissue |
Dominated by fat cells. Forms supporting, protective pads around kidneys and various other structures | Adipose Tissue |
Consists of a loose network of reticular fibers and cells. Forms the framework of the spleen, lymph nodes and bone marrow | Reticular Tissue |
Types of Connective Tissue | Fibrous connective tissue, cartilage, bone and blood. |
Types of Loose Connective Tissues | Aerolar Tissue, Adipose Tissue, and Reticular Tissue |
Types of Dense Connective Tissue | Tendons and Ligaments |
Bands of Dense Connective Tissues. This forms bands or sheets and bind together the organs and muscles. Also forms a protective sheath around the kidneys, spleen, and nerves. | Fascia |
Adipose | Fat |
Framework into which the cells of tissue are embedded. | Extracellular Matrix |
Fibers that are strong and flexible but resist stretching; these are the most abundant fibers | Collagenous Fibers |
Occurs in networks and support small structures such as capillaries and nerve fibers | Reticular Fibers |
Made of protein called elastin these fibers can stretch and recoil like a rubber band | Elastic Fibers |
Cartlidge is fast to heal...True or False? | False |
Three types of cartilage | Hyaline Cartilage, Elastic Cartilage and Fibrocartliage |
What type of cartilage is found at the end of movable joints, at the point where the ribs attach to the breastbone, the larynx, and the supportive rings around the trachea? Also forms most of the fetal skeleton. | Hyaline |
What type of cartilage is flexible support to the external ear and epiglottis? | Elastic Cartilage |
What type of cartilage forms the discs between the vertebrae and in the knee joint because this cartilage resists compression and absorbs shock? | Fibrocartilage |
Osseous Tissue | Bone |
Contains mineral salt crystals | Osseous Tissue/Bones |
Stores Calcium | Bones |
Bone has a rich blood supply? True or False? | True |
Unique among the connective tissues in that it exist as a fluid | Blood |
Which connective tissue doesn't contain any fibers? | Blood |
Cartilage is composed of cells called? | Chondrocytes |
Cartlidge has a rubbery, flexible matrix? True or False? | True |
Has a high degree of excitability and conductivity | Nervous Tissues |
The units that conduct nervous impulses | Neurons |
What protects and assists the neurons? | Neuroglia |
Soma | large cell body of the neuron |
Dendrites | extends from the soma, multiple, short processes. |
Contains a single, long nerve fiber and transmits signals to other cells | Axon |
Consists of long, thin cells called muscle fibers | Skeletal Muscle |
Joined together with junctions called intercalated discs. These junctions allow electrical impulses to spread rapidly from cell to cell; this rapid transmission permits almost simultaneous stimulation and contraction. | Cardiac muscle |
Cardiac muscle is why type of muscle? | Involuntary |
Cardiac muscle is striated. True or False? | True |
Smooth muscle consists of long, spindle shaped cells and lacks the striped pattern of striated muscle. Is smooth muscle voluntary or involuntary? | Involuntary |
What type of muscle lines the walls of many organs, including those of the digestive, respiratory, and urinary tract? | Smooth Muscle |
What occurs when damage tissue cells are replaced with the same type of cells, resulting in functional new tissue? | Regeneration |
What occurs when damaged tissue is replaced with scar tissue? | Fibrosis |
What are the 2 ways that tissue can repair itself? | Regeneration and Fibrosis |
When a wound is healing, the newly formed tissue is called? | Granulation Tissues |
Secretes collagen in the granulation tissue? | Fibroblasts |
Cutaneous Membrane is known as the ? | Skin |
Membrane that lines the body cavities is actually one continuous sheet. | Serous Membrane |
Membrane that surrounds each lung and lines the thoracic cavity | Pleura |
Membrane that surrounds the heart | Pericardium |
Membrane that lines the abdominal cavity and covers the abdominal organs | Peritoneum |
Cartlidge forming cells | Chondrocytes |
Columnar Epithelium | Epithelial tissue composed of cells having a tall, columnar shape |
Cuboidal Epithellum | Epithelial tissue consisting of cells having a cube- like shape |
Endocrine gland | A gland that secretes its product, called a hormone, directly into the bloodstream |
Epithelium | the layer of cells forming the epidermis of the skin and the surface layer of mucous and serous membranes |
Exocrine Gland | A gland that secretes its product into a duct, which then empties onto a body surface or inside a body cavity. |
Goblet Cell | modified columnar cell containing secretory vesicles that produce large quantities of mucus |
Mucous membrane | Epithelial membrane that lines body surfaces that open directly to the body's exterior |
Muscle Tissue | Tissue consisting of contractile cells or fibers that effect movement of an organ or body part |
Nervous Tissue | Tissue with a high degree of excitability and conductivity that make up the nervous system |
Osseous Tissue | Bone |
Bone-forming cells | Osteocytes |
Squamous Epithelium | Epithelium tissue consisting of thin, flat cells |
Stem Cells | Specialized cell that can differentiate into many different types of cells |
Tissue | Groups of similar cells that perform a common function |
Cardiac muscle is unique in that it doesn't depend upon stimulation by extrinsic nerves to contract. This is called ? | Automaticity |
Stratisfied means | more than one layer |
