Answer

Brief Explanations:

The dorsal column - medial lemniscus pathway is involved in transmitting sensations of fine touch, vibration, pressure, and proprioception. An injury to the dorsal column can lead to a loss of these sensations. Involuntary movements are mainly controlled by the basal - ganglia and other motor control centers. Homeostasis is regulated by various systems like the endocrine and nervous systems in a complex way and not directly by the dorsal column. The sleep - wake cycle is regulated by the hypothalamus and other brain regions. Motor control is mainly related to the corticospinal tracts and other motor pathways, not the dorsal column.

Answer:

A. loss of sensation to pressure and touch
