### 1. The dorsal root of a nerve contains what type of neurons?
a) Motor / Efferent
b) Sensory / Afferent
c) Interneurons
d) Both motor and sensory neurons
Correct Answer: b) Sensory / Afferent
Rationale: The dorsal root contains sensory (afferent) neurons that bring
information from the periphery into the spinal cord, whereas the ventral root
contains motor (efferent) neurons that send signals from the spinal cord to
muscles.

### 2. This part of the autonomic system accelerates the heartbeat
and increases breathing rate.
a) Parasympathetic nervous system
b) Sympathetic nervous system
c) Somatic nervous system
d) Enteric nervous system
Correct Answer: b) Sympathetic nervous system
, Rationale: The sympathetic nervous system is responsible for the "fight or
flight" response, which includes increased heart rate and respiratory rate.
The parasympathetic system slows these functions.
### 3. Name and describe what is occurring in the neuron cell
membrane in section 2 of the diagram. Include the charge of the
membrane during this phase.
