Tissues Flashcards
Simple
One layer of cells
Stratified
More than one layer of cells
Tight junction
Prevents passage of water and solutes between cells
Gap junction
Allows for the passage of water and solutes through the cell
Desmosomes
Tie adjacent cells together
4 types of tissues
- epithelial tissue
- connective tissue
- muscle tissue
- neural tissue
Functions of epithelial tissue
- physical protection
- control permeability
- provide sensation
- provide specialized secretions
Endocrine
Release hormones into interstitial fluid
Exocrine
Release secretions onto epithelial surface via ducts
Merocrine mode of secretion
Produced in Golgi and released by vesicles
Apocrine mode of secretion
Produced in Golgi, apical section of cell is filled with vesicles, cytoplasm is shed
Holocrine mode of secretion
Entire cell filled with secretion, cell bursts
Serous glands
Watery secretions that contain enzymes
Mucous glands
Release mucins that hydrate into mucus
Mixed glands
Release both watery secretions and mucins
Two types of supporting connective tissue
Cartilage and bone
Two categories of glands
Tubular and aveolar
6 functions of connective tissue
- structure
- transportation
- protects organs
- supports and connects of tissues
- store energy
- defend from microorganisms
Cutaneous membrane is also known as our
Skin
4 types of membranes
- mucous
- serous
- cutaneous
- synovial
3 types of muscle tissue
- smooth
- cardiac
- skeletal
Two nervous tissue cell types
- neurons
* neuroganglia
3 types of cartilage
- hyaline
- elastic
- fibrous
Function of hyaline cartilage
- Stiff but flexible support
* reduce friction
Function of fibrous cartilage
- prevents bone to bone contact
* limits movement of joints
3 fibers in connective tissue
- collagen
- reticular
- elastic
Ground substance
Fills spaces between cells
