ALHS 1011 CHAPTER 9 & 10 EXAM QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
Nervous and Endocrine Sytems - Answers Control of the body's billions of cells is accomplished in
party by 2 body-wide communication systems.
Organs of the Nervous System - Answers Brain, spinal cord, nerves, special sense organs (eyes and
ears), microscopic sense organs (skin).
Nodes of Ranvier - Answers a gap in the myelin sheath of a nerve, between adjacent Schwann cells.
Schwann cells - Answers Type of glia in the PNS, Supporting cells of the peripheral nervous system
responsible for the formation of myelin.
Dendrites - Answers receive messages from other cells (into the den)
Axons - Answers Carry impulses away from the cell body (a=way)
Sensory Neurons - Answers carry impulses from the sense organs from all parts of the body to the
spinal cord and brain
Motor Neurons - Answers carry impulses from the brain and spinal cord to muscles and glands. aka
efferent neurons
Interneurons - Answers conduct impulses from sensory neurons to motor neurons
Glia - Answers Greek work meaning "glue"
Glioma - Answers tumor composed of the glial tissue
Microglia - Answers Act as phagocytes, eating damaged cells and bacteria, act as the brains immune
system. Usually stationary, but in inflamed brain tissue they enlarge and move about.
Nerve - Answers group of axons bundled together like strands of cable
Nerve Impusle - Answers Sodium ion rushes into the neuron
Neurtotransmitters - Answers Chemicals acetycholine and dopamine are these, used by neurons to
communicate.
Synapse - Answers A junction where information is transmitted from one neuron to the next.
Epineurium - Answers Tough, fibrous sheath that covers the whole nerve.
Action Potential (AP) - Answers buildup of electrical current in the neuron, can travel over trillions of
routes
Layers of a nerve - Answers endoneurium, perineurium, epineurium (interior to exterior)
Two-Neuron reflex - Answers sensory neuron and motor neuron are involved
Three-Neuron relex - Answers Sensory, motor, and inter-neuron are involved.
Synaptic Cleft - Answers Space between a synaptic knob and the plama membrane of a postsynaptic
neurons. Its a narrow space.
catelcholamines (neurotransmitter) - Answers dopamine, norepinephrine, epinephrine. Plays a role in
sleep, motor function, mood, and pleasure recognition.
Diencephalon - Answers hypothalamus, thalamus, pineal gland. Small but important part of the brain
located between the mid-brain below the cerebrum above.
Hyptholamus - Answers Neurons here function as endocrine glands. Regulates water balance, sleep
cycles, and the control of appetite and emotions invovled in pleasure, fear, anger, sexual arousal, and
pain. Production of ADH occurs here.
Thalamus - Answers Associated sensations with emotions.
Gyri - Answers ridges of the brain
Sulci - Answers grooves in the brain
Corpus collosum - Answers the large band of neural fibers connecting the two brain hemispheres and
carrying messages between them
Occipital lobe - Answers Visual area of the cortex that helps you identify and understand specific
images.
Pia matter - Answers innermost membrane covering the spinal cord itself
autonomic nervous system (ANS) - Answers Consists of 2 divisions: sympathetic and parasympathetic
division.
Thorocolumbar system - Answers Sympathetic system is referred to as this.
releases acetylcholine (which relaxes the body) - Answers Sympathetic pre-ganglionic axon,
parasympathetic pre-ganglionic axon
Releases norepinephrine - Answers sympathetic post-ganglionic axon
autonomic nervous system (ANS) - Answers Regulates body's automatic, involuntary functions in
ways that maintain or quickly restore homeostasis. Consists of cardiac and smooth muscle and
glandular tissue.
