TEST BANK COMPLETE QUESTIONS
SOLUTIONS GRADED A+
◉ Neurons.
Answer: the basic functional units of the nervous system; cells that send
and receive signals
◉ Neuroglia.
Answer: cells that support and protect neurons
◉ Central Nervous System.
Answer: brain and spinal cord; contains neural tissue, connective tissues,
and blood vessels; processes and coordinates sensory data from inside
and outside the body, motor commands control activities of peripheral
organs, and higher functions of the brain: intelligence, memory,
learning, and emotion
◉ Nerves.
Answer: axons of neurons
◉ Peripheral Nervous System.
Answer: includes all neural tissue outside the CNS; delivers sensory info
to the CNS and carry motor commands from the CNS to peripheral
tissues and systems
,◉ Cranial Nerves.
Answer: connect to the brain
◉ Spinal Nerves.
Answer: attach to spinal cord
◉ Tract.
Answer: a bundle of axons in the CNS
◉ Nerve.
Answer: a bundle of axons in the PNS
◉ Afferent Division.
Answer: approaches CNS; carries sensory info; from PNS sensory
receptors to CNS
◉ Efferent Division.
Answer: exits CNS; carries motor commands; from CNS to PNS
muscles and glands
◉ Receptors.
Answer: detect changes or respond to stimuli; can be found on neurons
and specialized cells
,◉ Effectors.
Answer: respond to efferent signals coming from CNS (cells and organs)
◉ Somatic Nerous System.
Answer: controls voluntary and involuntary (reflexes) skeletal muscle
contractions
◉ Autonomic Nervous System.
Answer: controls subconscious actions, contractions of smooth muscle
and cardiac muscle, and glandular secretions; sympathetic division and
parasympathetic division
◉ Sympathetic Division.
Answer: stimulating effect (fight or flight response)
◉ Parasympathetic Division.
Answer: relaxing response
◉ Cell Body.
Answer: soma
◉ Dendrites.
Answer: used to receive information
, ◉ Axon.
Answer: sends info (electrical signals) away from the soma towards a
target cell
◉ Perikaryon.
Answer: cytoplasm
◉ Mitochondria.
Answer: produce energy
◉ Neurotransmitters.
Answer: chemical messengers used in signaling other cells
◉ Neurofibrils.
Answer: bundles of neurofilaments that provide support for dendrites
and axons
◉ Dendrites.
Answer: highly branched, each branch contains studded processes called
dendritic spines
◉ Chemical Gradient.
Answer: concentration gradient (Na+, K+)
