tissues Flashcards
four primary types of body tissues
epithelial(epithelium)
connective
muscle
nervous
epithelial tissue locations
body coverings
body linings
glandular tissues
epithelial tissue functions
Protection
- Absorption
- Filtration
- Secretion
Classification of Epithelia
simple and stratified
what are simple epithelia
one cell layers
what are stratified epithelia
more than one layer
classification of epithelia
squamous
cuboidal
columnar
locations and function of simple squamous
lines body cavities
lines lungs and capillaries
usually forms membranes
simple cuboidal locations
Common in glands and their ducts -
Forms walls of kidney tubules
covers the ovaries
simple columnar location
line’s digestive track
pseudostratified columnar locations
respiratory track where it is ciliated
stratified epithelia are also known as
transitional epithelium
what are stratified epithelium
composed of modified stratified squamous epithelium
where are stratified epithelium located?
lines the organs of the urinary system
glandular epithelium has?
glands
two major types of glands and explain them
Endocrine gland
- Ductless since secretions diffuse into blood vessels
- All secretions are hormones
Exocrine gland
- Secretions empty through ducts to the epithelial surface
- Include sweat and oil glands
Found everywhere in the body
- Includes the most abundant and widely distributed tissues
connective tissue
connective tissue functions
Binds body tissues together
Supports the body
Provides protection
bones are also called as
osseous tissue
types of connective tissues
bones
hyaline cartilage
blood
blood is also called as
vascular tissue
the most common type of cartilage
hyaline cartilage
Functions to protect and support the
body
bone(osseous tissue)
is composed of abundant collagen fibers and rubbery matrix
hyaline cartilage
where are hyaline cartilage usually found
Larynx
Entire fetal skeleton prior to birth
Functions as a more flexible skeletal
Blood cells surrounded by fluid matrix called?
blood plasma
Functions as the transport vehicle for
materials
blood(vascular tissue)
its function is to produce movement
muscle tissue
three types of muscular tissue
skeleton
cardiac
smooth
found only in the heart
cardiac muscle
what is the characteristic of a cardiac muscle cell
it is striated
Cells are attached to other cardiac muscle cells at
intercalated disks
involuntary control vs involuntary muscle
control is for the cardiac muscle
muscle is for the smooth muscle
Found in walls of hollow organs such as stomach, uterus, and blood vessels
smooth muscle
where are smooth muscles found
Found in walls of hollow organs such as stomach, uterus, and blood vessels
Characteristics of smooth muscle cells
No visible striations
One nucleus per cell
- Spindle-shaped cells
nervous tissue are composed of
Composed of neurons and nerve support cells
nervous system is composed of neurons and nerve support cells called
neuroglia
functions is to send impulses to other areas of the body
nervous tissue
nervous tissues are responsible for
Irritability – able to respond to stimuli Conductivity – able to conduct impulses
