Muscle Tissue and Nervous Tissue

Muscle Tissue types

Smooth, Skeletal, Cardiac

Muscle cells are also called

muscle fibers

muscle tissue is highly specialized to

contract or shorten to produce movement

cardiac muscle cell

smooth muscle cell

smooth muscle

smooth muscle cell shape

spindle

smooth muscle cells contain how many central nuclei

one

skeletal muscle

is skeletal muscle striated

yes

forms mucous, serous

skeletal muscle cell shape

long cylinders

skeletal muscle (striated/unstriated)

striated

skeletal muscle is attached to

the skeleton

cardiac muscle junctions between cells are called

intercalated discs

nervous tissue function

transmit electrical signals to regulate & control body functions

nervous tissue makes up

brain, spinal cord, and peripheral nerves

nervous tissue cell types

neurons and neuroglia

neurons

generate and conduct nerve impulses

neuroglia

non-conducting supporting cells

neuron signal direction

dendrites, cell body, axon, axon terminals.

cell body (neuron)

cell´s life support center

Dendrites

recieve messages from other cells

Axon

passes messages away from the cell body to other neurons, muscles, or glands

neural impulse

electrical signal traveling down the axon
