1What is a Tissue2


2/16

A group of closely associated

cells that perform related

functions and are similar instructure. Those structures are

constituted by an organized cell

set equeal evenly distribuited,

with a coordinated physidogical

behavior and commonembryonic, it’s called histology:

science that studies these

Animal Tissues

-pithelium: The primary

functions of epithelial tissues

are: !-"rotect the tissues thatlie beneath it from

radiation,desiccation,to#insmin

vasion by pathogens,and

regulation and e#change of

chemicals between theunderlyng tissues and body

cavity, & to provide sensation. '

(ecretion of hormones into the

blood vascular system

)onnective Tissue

)onnective tissue *)T+ is one of

the four types of

biological tissue that supports,

connects, or separates dierent

types of tissues and organs inthe body.

uscle Tissue


6/16

uscle is a soft tissue found in

most animals. uscle

cells contain protein lamentsof actin and myosin that slide

past one another, producing

a contraction that changes both

the length and the shape of the

cell.

/ervous tissue is the main

component of the two parts ofthe nervous system$

the brain and spinal cord of

the central nervous

system*)/(+, and the branching

peripheral nerves of

the peripheral nervous

system *"/(+, which regulates

and controls bodily functions

and activity.
