Introduction to Tissues

Muscle Tissue
Function: specialize in contractions for movement; voluntary (walking,
speech) and involuntary (pushing materials through the body).
This has been created for educational purposes as a review of muscle and nerve
tissues. Pictures have been found on a variety of online resources.

determines the diameter of
blood vessels

Nerve Tissue
Function: processes sensory information from sensory organs and
responds with motor instruction to the body muscles and glands.
Nerve Tissue
Classification:

Neurons: cells responsible
for retrieving, interpreting
and sending the electrical
signals of the nervous
system.

Neuroglia / Glial cells:
support cells that surround
and wrap neurons

Structure of Neurons
glial cell that increases the
speed of message transmission
Schwann cells /
\ axon
soma /
transmits messages down neuron
towards a muscle or gland
axon terminals /
communicates with adjacent
cells via neurotransmitters
dendrites /
collects sensory messages
to send to cell body
