chapter 4 study guide Flashcards
1
Q
structural and functional characteristics of epithelial tissue
A
- simple- single layered
- stratified- several layers of cells
- squamous- flat and thin
- cuboidal- cube-shaped
- columnar- taller than wide
- regenerate quickly
- protects body from skin to organs
2
Q
various types of epithelia
A
- simple squamous epithelium
- air sacs of the lungs and the lining of the heart
- allows materials to pass through by diffusion and secretes lubercating substances
- stratified squamous epithelium
- lines the vagina, esophagus, and mouth
- protects against abrasion
- stratified cuboidal epithelium
- sweat glands, salivary glands, and the mammary glands
- protective tissue
3
Q
gland
A
consists of one or more cells that make and secrete a particular product
4
Q
difference between exocrine and endocrine glands
A
- exocrine glands are classified by structure, they secrete substances onto the surface of epithelial tissues through a duct or tube ex) sweat and tears
- endocrine glands are ductless and secrete horomones directly into the blood or lymph
5
Q
characteristics of connective tissue
A
- composed mainly of extracellular matrix that seperates the cells
- fibers of connective tissue provide support
- collagen fibers make them strong to provide strength
- elastic fibers allow them to stretch and recoil
6
Q
connective tissue found in the body
A
- adipose tissue- contains lipids, stores fat, helps keep heat in the body
- reticular tissue- provides a supportive framework for soft organs
*dense regular connective tissue- consists of collagenous fibers packed into parallel bundles - dense irregular- consists of collagenous fibers interwoven into a mesh like network
7
Q
compare and contrast the three types of muscle tissue
A
- skeletal muscle attaches to the skeleton and produces voluntary body movement. have prominent striation of nuclei
- cardiac muscle is responsible for in movement of the heart. have a single nucleus appear striations
- smooth muscle is found in the walls of hollow organs. no visiable striations
8
Q
indicate the general characteristics of nervous tissue
A
- made up of neurons and neuroglia
- cells of nervous tissue are specialized to transmit and recieve impulses
9
Q
function of cutaneous membrane
A
- skin
- firmly attached to a thick layer of dense irregular tissue
- protects
10
Q
function of mucous membrane
A
- line the body cavities that open to the exterior
11
Q
function of serous membrane
A
- rests on a thin layer of areloar tissue
- covers organs within cavities
12
Q
process of tissue repair involved in normal healing of a superficial wound
A
- clot stops any blood vessel damage
- injuried cells release chemicals to attract white blood cells
- collagen fibers are laid at random
- epithelial cells fill in
- blood supply is restored
- scab falls off
