EXAM WITH ELABORATED QUESTIONS AND
ANSWERS 2026/2027
1. the neuron pictured below, is best described as:
2. true or false, explain why the state is false : Bipolar neurons have a central
cell body with two extensions: true
3. List the phases of an action potential in order: 1. resting potential
2. depolarization
3. repolarizarion
4. resting condition
4. true or false , if false explain why the statement is false: the central nervous
system consists of the brain and spinal cord: true
5. name and describe what is occurring in the neurocell membrane in section 2
of the diagram. include the charge of the membrane during this phase: deprivation,
sodium gates are opened and the sodium floods into the axon admits the depolarization of the action potential, causing
the charge voltage to go from 0 to +40 mV
6. This part of a reflex is inside the CNS, made up of one or more synapses.: in-
tegration center
7. match the following lobes of the brain with the correct function: temporal - contains
sensory areas for hearing and smelling
frontal- contain higher levels ex..
pariteal - receives sensory info from body receptors
occipital - interprets visual input
8. which of the following structures of the spinal cord contains the cell bodies
of afferent neurons: dorsal root ganglion
9. what is true about the flexor withdrawl reflex: A&d (IT DOES NOT INVOLVE INTERNEURONS &
, THE EFFECT OF THE REFLEX IS TO CREATE A CO-CONTRACTION OF 2 MUSCLES
10. Label the nerves (A-C) in the figure below:
A:
B:
