Physio muscle and nervous tissue

muscle tissue function

A body tissue that contracts or shortens, making body parts move.

mycocytes

muscle cells

muscle tissue types

skeletal, cardiac, smooth

Fibrosis

the thickening and scarring of connective tissue, usually as a result of injury.

Does muscle tissue undergo mitosis/regeneration?

No

skeletal muscle function

voluntary movement; locomotion; manipulation of the environment; facial expression; voluntary control

Is skeletal muscle voluntary or involuntary?

voluntary

Is skeletal muscle striated?

yes, it's striated

is skeletal muscle easily fatigued?

yes

Are skeletal cells multinucleated or uninucleated?

multinucleated

striated

marked with thin, narrow grooves or channels; striped

Where is cardiac muscle found?

only in the heart

cardiac muscle tissue function

as it contracts, it propels blood into the circulation

Is cardiac muscle voluntary or involuntary?

involuntary

Are cardiac muscles striated?

Yes, cardiac muscles are striated

are cardiac muscle cells multinucleate or uninucleate?

uninucleate

is the cardiac muscle easily fatigued?

No

smooth muscle tissue location

walls of internal organs, digestive tract, blood vessels, urinary bladder

visceral

pertaining to the internal organs

Is smooth muscle voluntary or involuntary?

involuntary

Is smooth muscle striated?

non-striated (no)

smooth muscle function

propels substances or objects (foodstuffs, urine, a baby) along internal passageways; involuntary control

is smooth muscle tissue uninucleate or multinucleate?

uninucleate

is smooth muscle tissue easily fatigued?

no

Persistalsis

Waves of circular muscle contractions to squeeze and push boluses along the gut.

nervous tissue function

Transmit electrical signals from sensory receptors and to effectors (muscles and glands) which control their activity

nervous tissue location

brain, spinal cord, nerves

Irritability

ability to respond to a stimulus and convert it into a nerve impulse

Conductivity

able to transmit impulse to other neurons

nerve cells

neurons

does nervous tissue undergo mitosis?

no

types of neurons

sensory, motor, interneurons

sensory neurons

neurons that carry incoming information from the sensory receptors to the brain and spinal cord

motor neurons

neurons that carry outgoing information from the brain and spinal cord to the muscles and glands

internuerons

neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs

inflammation

a localized response to an injury or to the destruction of tissues

immune response

The body's defensive reaction to invasion by bacteria, viral agents, or other foreign substances.

Regeneration

replacement of destroyed tissue by the same kind of cells

scar tissue

fibrous connective tissue that binds damaged tissue

Immediate response is connected to what tissue?

nervous tissue

Neuroglia

cells that support and protect neurons
