Animal Tissue (3.5) Flashcards
are groups of many similar cells that
perform the same specific function
Tissues
What are the four tissue types
- Epithelial tissue
- Connective
- Muscle
- Nervous
– Closely packed sheets of cells anchored on a basement membrane
– Cover surfaces and line the cavities and tubes of internal organs (apical
and basal surfaces)
– Held by tight junctions and desmosome
– Avascular (no blood vessels) but enervated
– Regenerative
epithelial tissues
Functions of Epithelial tissues: ‒ P\_\_\_\_ ‒ E\_\_\_\_: Secretion, absorption ‒ E\_\_\_\_-waste products ‒ S\_\_\_\_
‒ Protection
‒ Exchange: Secretion, absorption
‒ Excretion-waste products
‒ Sensation
______- (lining the air sacs of the lung)
______- (forming a tube in the kidney)
______-(lining the intestine)
______-(lining the esophagus)
Simple squamous epithelium
Simple cuboidal epithelium
Simple columnar epithelium
Stratified squamous epithelium
type of epithelium in mouth, blood vessels, heart, lung air sacs and outer layers of the skin
Squamous
type of epithelium in Glands and their ducts, and the lining of the kidney tubules ( secretion and Absorption)
Cuboidal
type of epithelium
– lining of the stomach and intestines
– Some specialized for sensory reception: nose, ears and taste buds of
the tongue
Columnar
Stratified epithelium
– Keratinized top layer (tough)- ___
– Un-keratinized top layer- _____
skin
mouth cavity
Epithelial tissue on the interior body surfaces
is known as ____
endothelium
Structure
• characterized by few cells in and large amount of
extracellular non-living matrix secreted by its cells
Connective Tissue
Functions
• binds and supports other tissues
• Movement
• Many others
connective tissue
o sponge-like scaffold of a tensile protein
Collagen
oSpecialized cells with extracellular matrix and proteins
collagen and elastin
Cartilage
o living and dead cells in the mineralized organic matrix
o hardened by calcium phosphate and calcium carbonate
deposits
Bone
___-connect bones to bone
____-connect muscle to bone
Ligaments
Tendons
• Fibers made of many fused cells that have contractile
proteins and multiple nuclei
Muscle Tissue
function of muscle tissue
Movement & mechanical work
Three types of muscles
‒ ____: voluntary body movements
‒ ____ : pumps blood
‒ ____: involuntary moves the walls of internal hollow
organs, such as the GI, arteries, bladder, uterus.
Skeletal
Cardiac
Smooth
• Neurons that make up the brain, spinal cord and
peripheral nerves that branch throughout the body
Nervous Tissue
Branching neurons made of a cell body and have
cell extensions: ___, and ___
axon; dendrites
Function
• Communication network
• Transmit nerve signals rapidly to control body
activities
nervous tissues
An ____is made of several tissues that
collectively perform specific functions
organ
