Question

Describe the physiological role of the dorsal and ventral spinocerebellar tracts of the spinal cord. State the location of the primary and secondary cell bodies in the spinocerebellar pathway.

A) Transmit motor signals from the brain to the muscles; primary cell bodies in the cerebellum.
B) Transmit sensory information to the brain; primary cell bodies in the spinal cord.
C) Control respiratory functions; primary cell bodies in the brainstem.
D) Regulate blood pressure; primary cell bodies in the thalamus.

Answer 1

The dorsal and ventral spinocerebellar tracts transmit sensory information to the brain and compare it with motor commands. The primary cell bodies are in the spinal cord and pons.

Step-by-step explanation:

The dorsal and ventral spinocerebellar tracts of the spinal cord play a role in transmitting sensory information to the brain and comparing it with motor commands from the cerebrum. The primary cell bodies in the spinocerebellar pathway are located in the spinal cord and pons.
