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