Human Tissues Flashcards
1
Q
epithelia
A
- layers of cells that covered expose surfaces and line internal cavities and passageways
- no blood vessels and often regenerate quickly to replace dead and damage cells
2
Q
squamous
A
appears flattened
3
Q
cubodial
A
cubes
4
Q
columnar
A
tall columns
5
Q
simple
A
1 row
6
Q
stratified
A
multiple rows
7
Q
pseudostratified
A
when cells in one row but nuclei of cells appear stratified
8
Q
avascular
A
receive nutrients from substance that diffuse through blood vessels of underlying connective tissue
9
Q
glands
A
- substances that are made up of EPITHELIAL TISSUE and involved in secretion of fluids
- synthesize substances and then release them into bloodstream, into inner body or surface
10
Q
epithelial tissues
A
- PROTECT underlying tissue from toxin and physical trauma
- ABSORB substances in digestive tract lining
- REGULATE and EXCRETE chemicals between bpdy cavities and underlying tissue surfaces
- SECRETE hormones in vascular system
- DETECT sensation
11
Q
connective tissue
A
- fills internal space and never exposed to outside of body
- PROVIDES STRUCTURAL SUPPORT FOR BODY AND STORES ENERGY
- made up of cells, ground substances, and fibers
12
Q
muscle tissue
A
- specialized for contraction, which is the force that produces movements
- help maintain body structure (posture) and controlling body temp
13
Q
neural tissue
A
- conducts ELECTRICAL impulses, which help send info and instructions through-out body
- mostly concentrated in brain and spinal cord
14
Q
neurons
A
transmit and receive impulses
15
Q
neuroglia
A
provide nutrients to neurons and help pass impulses from neurons through tissue
