Flashcards in Tissues Deck (20):
1

Functions of epithelial tissues

Provide physical protection, control permeability, absorption, and produce secretions

2

Basement membrane

Bottom layer that is attached to connective tissues

3

Two criteria epithelial tissue is classified by

Shape and layers

4

Avascular

Lacking blood vessels

5

Simple epithelial functions

Filtration, diffusion, secretion, absorption

6

Stratified epithelial tissue

More resistant to wear

7

Transitional epithelium

Can contract and stretch out

8

Characteristics all connective tissues have in common

Specialized cells, solid extra cellular protein fibers, fluid "ground substance"

9

Functions of connective tissues

Support and protection, transportation of materials, storage of energy reserves, defense of the body

10

Extra cellular matrix

Extra cellular components of connective tissues, it is the majority of tissue volume

11

Three types of cartilage and where they are found in the body

Hyaline- synovial joints, rib tips, sternum, and trachea
Elastic- external ear and epiglottis
Fibrous- found between pubic bones and intervertebral discs

12

Muscle tissue functions

Contract in order to provide movement

13

Skeletal

Striated, multinucleated, voluntary, attached to connective tissues

14

Cardiac

Striated, uninucleated, involuntary, found in heart

15

Smooth

No striations, uninucleated, involuntary, found in the walls of hollow organs

16

Nervous tissue functions

Conduct electrical impulses, senses internal or external environments, processes information, and controls responses

17

Nervous tissue location

The brain and the spinal chord

18

Two types of cells and how they are different

Neurons- nerve cells that perform electrical communication
Neuroglia- supporting cells that repair and supply nutrients to the neurons

19

Three parts of a neuron

Dendrite, cell body, axon

20

Location of epithelial tissues

Skin, lining of digestive, urinary, reproductive, respiratory tracts, lining of body cavities, lining of fluid filled brain cavities, lining of blood vessels and heart
