Final answer:
Smooth muscle cells lack transverse tubules, have a single nucleus, and are under involuntary control, fitting the description provided by the student, making B. smooth muscle the correct answer.
Step-by-step explanation:
The type of muscle cell that is described in the student's question as lacking transverse tubules, having a single nucleus, and being controlled involuntarily is the smooth muscle.
Smooth muscle cells are characteristically spindle-shaped with a centrally located single nucleus and lack the striations seen in skeletal and cardiac muscle cells. Smooth muscle is found in the walls of blood vessels and in the digestive, reproductive, and urinary systems where it helps to move substances through these systems.
The movement of smooth muscle is governed by the autonomic nervous system and it reacts to local conditions in the tissues, operating without voluntary control by the individual. Hence, the correct answer to the question is B. smooth muscle.
