Unit 3 Lecture Study Guide
1. List the 4 primary tissue types and give the general characteristics and functions of each one.
1) Epithelial: Covers the body, lines the cavities, tubes ducts and blood vessels, covers the organ inside the body cavity
2) Connective: most abundant& widely distributed, connect, bind and supports structures, insulates, and transports substances.
3) Muscle: associated with the bones of the skeleton, the heart and in the walls of the hollow organs of the body. Movement, locomotion, maintains posture, produces heat, facial expressions, pump blood, and peristalsis.
4) Nervous: main component of the nervous system. Regulates & controls body functions, generates & transmits nerve impulses, supports, insulates and protects impulse generating neurons.
2. How are epithelial tissues classified?
-Closely attached to each other to form a barrier
-One free apical surface open to the outside
-One fixed basal surface attached to underlying connective tissue
-No blood vessels
-Can have lots of nerves
-Very good at regenerating
3. How does the type of epithelial tissue relate to its function? Give at least 1 example of where you would find each type of epithelial tissue.
-Squamous: simple one cell thick-sometimes stratified: skin
-Cuboidal: one cell thick- lines the kidneys—reabsorption
-Columnar: one cell thick- lines digestive tract
4. Differentiate between exocrine and endocrine glands. Give an example of each.
Endocrine glands are ductless glands that have lost connection with the surface. The secretions diffuse directly in to the blood vessels.(Pituitary Gland)
Exocrine glands are glands with excretory ducts that lead secreted material from the glad to the surface. (Saliva Gland)
5. What is the difference between apocrine, merocrine and holocrine glands? Which is the most
