Bio 102 NVCC Terranova Final questions with
verified answers
Central Nervous System Ans✓✓-the brain and spinal cord
main control center
takes in sensory information
organizes and synthesizes this input
provides instructions for motor output to the rest of the body
Peripheral Nervous System Ans✓✓-nerves connecting the brain and spinal cord
to other parts of body
Subparts:
Sensory and Motor
Motor:
somatic and autonomic
Autonomic:
sympathetic and parasympathetic
Neuron Ans✓✓-nerve cells that transmit electrical signals throughout the body
axon Ans✓✓-Take information away from the cell body to other cells
Single, long projection
Dendrites Ans✓✓-Bring electrical signals to the cell body
Numerous short projections
, cell body Ans✓✓-contains organelles
sensory neurons Ans✓✓-send signals from receptors to CNS
Interneurons Ans✓✓-located in CNS
integrate info
send info to other interneurons or motor neurons
motor neurons Ans✓✓-send info from CNS to muscles or glands
sensory receptor Ans✓✓-cells that detect stimuli
-Charge outside plasma membrane
-Charge in the cell
-Caused by differences in relative amounts of Na and K ions Ans✓✓-Describe the
electrical charges inside and outside a neuron when it is at rest (i.e., when it's not
sending an electrical signal). What causes these electrical charges?
synapse Ans✓✓-the place where one neuron sends a signal to a neighboring
neuron
1. The axon terminal experiences depolarization
2. Synaptic vesicles are released from their anchors
3. Synaptic vesicles fuse with cell membrane
