What are parasympathetic efferents?
What are parasympathetic efferents?
The facial nerve carries parasympathetic efferents, which are responsible for controlling certain bodily functions.
What are sensory afferents?
What are sensory afferents?
The facial nerve contains sensory afferents that bring sensory information from the face and mouth.

Study Notes
Facial Nerve Anatomy
-
The facial nerve has two main parts:
- (a) Parasympathetic efferents and sensory afferents
- (b) Motor branches to muscles of facial expression and scalp muscles
-
The diagram shows numbered structures. These numbers likely correspond to labels on the diagram, showing different components of the facial nerve and their connections.
