Question

Quizplus · Accepted Answer

Cardiac muscle cells have gap junctions that allow them to work in a coordinated fashion, a single nucleus per cell, and a high number of mitochondria to meet their energy needs. They are also striated like skeletal muscle but function involuntarily, unlike skeletal muscle which is under voluntary control. Smooth muscle is not striated and functions involuntarily, skeletal muscle is striated and functions voluntarily, striated columnar epithelium does not exist as a tissue type, and nervous tissue is involved in signaling rather than contraction.
