Consists of the extensive network of spinal nerves carrying sensory
Peripheral Nervous System (PNS) or afferent information towards the spinal cord and brain and motor
or efferent information away from the brain and spinal cord.
afferent fibers transmit impulses from organs to CNS
efferent fibers transmit impulses to organs from CNS
voluntary control of skeletal
somatic nervous system
muscles ex: chewing food

involuntarily controls the visceral muscles
of organ systems like the digestive and
autonomic (visceral) nervous system cardiovascular systems. Controls the
contraction and relaxation of visceral
reflexes.
ex: digestion, heartbeat
gathers information and carries it to the CNS. The senses gather the
sensory neurons
information that the sensory nervous system transmits
motor nerves carry impulses away from the CNS to the effectors
ventricles (brain) canals in the brain that contain cerebrospinal fluid
Fluid in the space between the meninges that acts as a shock absorber
cerebrospinal fluid
that protects the central nervous system.
part of brain found at the very bottom (near neck) of the skull and
cerebellum
coordinates body movements, posture, and balance
found between the thalamus and the spinal cord. Lowest part of the
brainstem
brain. Supports unconscious functions like breathing, heart rate, and
blood pressure.
Largest part of the brain; responsible for interpreting touch, speech,
cerebrum
reasoning, and emotions
cerebral cortex grey matter that surrounds the entire cerebrum
gyri ridges
sulci shallow grooves
fissures deep grooves in the brain
processes high level cognitive skills, reasoning, concentration, motor
frontal lobe
skills, language.
integration site for visual perception and sensory information such as
parietal lobe
touch, pain, and pressure
temporal lobe Part of brain that controls hearing
occipital lobe interprets visual information
limbic system controls emotions and memory
plays role in regulating the autonomic nervous system. Primarily
Hypothalamus
concerned with homeostasis and regulates activities such as hunger,
anger and pain
amygdala this produces feelings such as anger, violence, fear, anxiety
thalumus sensory inputs come throught. Smell
hippocampus helps convert short term memory to long term memory
Largest part of a typical neuron; neuron cell body is
contains the nucleus and much of
the cytoplasm
the extension of a neuron, ending in branching terminal fibers, through
axon
which messages pass to other neurons or to muscles or glands
myelin sheath insulates the axon of some neurons and helps speed up neural impulses
A body tissue that covers the body surfaces, lines body cavities, and
epithelial tissue
serves as a protective barrier
connective tissue Connects other tissues to each other and serves to bind and support body parts
Muscle tissue Moves the body and its contents by contraction
Receives stimuli from the internal or external environment and
Nervous tissue
communicates through electrical impulses with the rest of the body
Sagittal plane (aka median) Lateral (left) or medial (right) division
frontal plane (aka coronal plane) Posterior (back) anterior (front) division
