Eye muscle. Transmission electron micrograph (TEM) of a section through a striated muscle cell from the ciliary muscle of a human eye,showing mitochondria (dark green) and sarcoplasmic reticulum (yellow) that separates the myofibrils (light green). Basal lamina tissue and collagen (white,bottom) surround the cell's membrane (purple). The ciliary muscle is a ring of striated smooth muscle in the eye's middle layer that is contracted to alter the curvature of the lens and focus light on the retina at the back of the eye.
