Part 7/14:
While their initial activation is myogenic, the autonomic nervous system modulates the intensity and rate of contraction in these muscles, adapting to the body's needs.
Types of Muscles: Structures and Roles
Skeletal Muscle
Voluntary and striated, these muscles are under conscious control, enabling precise movements. Contractions are initiated via neural stimulation, and their morphology involves multilayered organization of fibers and molecular components.
Smooth Muscle
Involuntary and non-striated, smooth muscles are found in walls of arteries, veins, digestive tract, and other organs. Their contractions are slower but sustained, suitable for regulating blood flow and organ functions.
