Question | Answer |
---|---|
four types of tissue | epithelium, connective, muscle, nervous |
characteristics of muscle. | provides movement for the body. contains fibers made up of myosin and actin protein filaments. |
function of epithelial. | absorption, secretion, and protection. |
characteristics of epithelial. | lines body cavities. covers free surfaces. includes ducts and glands. tightly connected to each other. exposed to a space on their free surface. tightly connected to deeper tissue called the basement membrane. |
characteristics of nervous. | conduct electrical impulses. composed of one cell type-the neuron. classified by function and structure. |
neurons have... | nucleus, several dendrites, and one or several axons. |
normal pathway of nerves follows... | dendrite to cell body to axon -produces a substance called a neurotransmitter -allows impulse to jump -neuron to neuron -neuron to muscle -neuron to gland |
functions of nerves. | sensory, motor, and association. |
structure of nerves. | unipolar, bipolar, and multipolar. |
location of simple squamos. | lungs, aveoli capillaries, ear cochlea, heart lining, serous membranes. |
simple squamos function. | rapid exchange: diffusion, osmosis, and filtration. |
simple squamos- general. | fried egg-scale like, saran wrap thin, joined end to end, and low wear and tear. |
characteristics of epithelial tissue. | has a free edge, packed end to end, avascular, and has nerve supply. |
simple cuboidal location. | kidney tubeles, glands, ducts, and anterior lens of the eye. |
function of simple cuboidal. | rapid exchange: secretion and absorption. |
simple cuboidal- general. | round nuclei. secretion of mucus, sweat, etc. |
simple columnar location. | GI tract from stomach to anus, ducts, glands, and gall bladder. |
simple columnar function. | secrete and absorb. |
simple columnar- general. | oval nuclei. contains microvilli (small hairs) and goblet cells. |
stratifed squamos location. | skin, mouth, vagina, esophagus, and eye. |
function of stratified squamos and stratified cuboidal. | protection. |
stratified squamos- general. | several layers, great wear, deep cell, can be cuboidal/columnar, keratinized=skin, nonkeratinized=mouth, esophagus, vagina, and tongue. |
stratified cuboidal location. | ducts of adult sweat glands. male uretha. |
stratified cuboidal- general. | circular nucleus. |
stratified columnar location. | submandibular salivary gland and male uretha. anal mucous membrane. |
stratified columnar function. | protect and secrete. |
