2026/2027
Central nervous system - ANS (CNS) brain and spinal cord.
peripheral nervous system - ANS Body Nerves that connect to the central nervous system
(brain and spinal cord). Connects the central nervous system to the body's organs and limbs.
sensory (afferent) neurons - ANS neurons that carry incoming information from the sensory
receptors (sight, smell, sound etc.) to the brain and spinal cord
Interneurons - ANS Central nervous system neurons that internally communicate and
intervene between the sensory inputs and motor outputs
motor (efferent) neurons - ANS Nerve cells responsible for making an action or movement
happen.Multipolar Shaped Neurons
white matter - ANS myelinated axons
grey matter - ANS unmyelinated neuron cell bodies and short, unmyelinated axons

,meninges - ANS three protective membranes that surround the brain and spinal cord. dura
mater, arachnoid mater, pia mater
dura matter - ANS thick, outermost layer of the meninges surrounding and protecting the
brain and spinal cord
arachnoid mater - ANS weblike middle layer of the three meninges
pia matter - ANS thin, delicate inner membrane of the meninges
cerebrospinal fluid - ANS Fluid in the space between the meninges that acts as a shock
absorber that protects the central nervous system.
dendrites - ANS Branchlike parts of a neuron that are specialized to receive information.
cell body (soma) - ANS the part of a neuron that coordinates information-processing tasks
and keeps the cell alive
axon hillock - ANS the cone-shaped area on the cell body from which the axon originates
axon - ANS the neuron extension that passes messages through its branches to other
neurons or to muscles or glands
Schwann cells - ANS Type of glia in the PNS, Supporting cells of the peripheral nervous system
responsible for the formation of myelin.

, myelin sheath - ANS covers the axon of some neurons and helps speed neural impulses
Nodes of Ranvier - ANS Gaps in the myelin sheath to which voltage-gated sodium channels
are confined.
axon terminals - ANS Branches at the end of the axon that contain tiny pouches, or sacs,
called synaptic vesicles.
Cerebrum - ANS Largest part of the brain; responsible for voluntary muscular activity, vision,
speech, taste, hearing, thought, and memory.
frontal lobe - ANS A region of the cerebral cortex that has specialized areas for movement,
abstract thinking, planning, memory, and judgement
parietal lobe - ANS portion of the cerebral cortex lying at the top of the head and toward the
rear; receives sensory input for touch and body position
temporal lobe - ANS A region of the cerebral cortex responsible for hearing and language.
occipital lobe - ANS A region of the cerebral cortex that processes visual information
functional areas - ANS areas of the brain that are specialized in the production of certain
tasks
corpus callosum - ANS the large band of neural fibers connecting the two brain hemispheres
and carrying messages between them
