Which of the following belong to special visceral efferent column
**Core Concept**
The special visceral efferent (SVE) column is a type of motor column in the spinal cord that controls voluntary movements of skeletal muscles. It is involved in the innervation of muscles that are responsible for actions such as mastication, swallowing, and eye movements. The SVE column is responsible for transmitting signals from the central nervous system to the muscles involved in these voluntary movements.
**Why the Correct Answer is Right**
The special visceral efferent (SVE) column is responsible for transmitting signals to muscles that are involved in voluntary movements such as mastication, swallowing, and eye movements. These muscles are innervated by cranial nerves that arise from the brainstem, such as the trigeminal nerve (cranial nerve V) and the facial nerve (cranial nerve VII). The SVE column is also involved in the innervation of muscles involved in speech and facial expressions.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the general somatic efferent (GSE) column is responsible for transmitting signals to skeletal muscles involved in voluntary movements, but it is not specific to special visceral functions like mastication and swallowing.
**Option B:** This option is incorrect because the special visceral afferent (SVA) column is responsible for transmitting sensory information from muscles and joints involved in special visceral functions, but it is not involved in the motor control of these muscles.
**Option C:** This option is incorrect because the general visceral efferent (GVE) column is responsible for transmitting signals to smooth muscle and cardiac muscle, which are not involved in special visceral functions like mastication and swallowing.
**Option D:** This option is incorrect because the general somatic afferent (GSA) column is responsible for transmitting sensory information from skeletal muscles and joints, but it is not involved in the motor control of these muscles.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the SVE column is responsible for controlling muscles involved in special visceral functions, which are innervated by cranial nerves that arise from the brainstem. This knowledge is crucial for understanding the anatomy and physiology of the cranial nerves and their clinical implications.
**Correct Answer:** C.
