Answer

Brief Explanations:

The dorsal column - medial lemniscus pathway is involved in transmitting sensations of fine touch, vibration, and proprioception. An injury to the dorsal column can lead to a loss of sensation to pressure and touch. Involuntary movements are mainly controlled by other neural structures like the basal ganglia and cerebellum. Homeostasis is regulated by multiple systems including the endocrine and nervous systems in a complex manner not directly tied to the dorsal column. The sleep - wake cycle is regulated by the suprachiasmatic nucleus and other brain regions. Motor control is mainly related to the corticospinal tracts and other motor - related neural pathways.

Answer:

A. loss of sensation to pressure and touch
