� Consists of neurons (nerve cells)
and neuroglial cells (1)
� Neurons are the functional cells
of nervous tissue (1)
� Locations: brain, spinal cord and
peripheral nerves (1)
� Functions: detect stimuli,
respond, and transmit
information to other cells (1)
� Key Features: few neurons with
cytoplasmic extensions and
multiple neuroglial cells (1)

� Found only in the heart
� Contractions provide the major force for moving
blood through the circulatory system. (1)

� Found in the walls of hollow
organs and tubes, the
internal muscles of the eye,
the walls of blood vessels,
and other areas. (1)
� Smooth muscle performs a
variety of functions,
including propelling urine
through the urinary tract,
mixing food in the stomach
and intestine, dilating and
constricting the pupils, and
regulating the flow of blood
through blood vessels.(1)

� With its associated connective tissue, constitutes about
40% of the body's weight and is responsible for
locomotion, facial expressions, posture, respiratory
movements, and many other body movements. (1)
� Function is to a large degree, is under voluntary, or
conscious, control by the nervous system. (1)

filtration, and osmosis
• Surface layers of pleura,
pericardium, and
peritoneum(mesothelium)
: absorption by diffusion,
osmosis and also

Locations: brain, spinal cord and
peripheral nerves
Functions: detect stimuli, respond, and
transmit information to other cells
Key Features: few neurons with
cytoplasmic extensions and multiple
neuroglial cells
• functional cells of nervous tissue
• transmit electrical signals
• three principal parts:
• the soma
• Dendrites
• one axon or nerve fiber.
• The soma contains the nucleus.
Extending from the soma are
dendrites that receive information
and transmit it towards the soma
and one axon that transmits
information away from the soma.

air passage of the
respiratory system
and certain
segments of the
male reproductive
system.
Pseudostratified
epithelia function in
secretion or
absorption.
