Skeletal muscle is made up of elongated cylindrical multinucleate cells, also called muscle fibers, that span the length of the muscle. Each muscle cells is surrounded by connective tissue called endomysium. Endomysium is similar in composition to basement membrane that underlies epithelia.

The contractile units of skeletal muscles are _____. A) microtubules B) mitochondria C) T tubules D) myofibrils Furthermore, what is the smallest contractile unit in muscle? The smallest contractile unit of skeletal muscle is the muscle fiber or myofiber, which is a long cylindrical cell that contains many nuclei, mitochondria, and sarcomeres (Figure 1). Each muscle fiber is surrounded by a thin layer of connective tissue called the endomysium.

The Motor Unit Skeletal muscle is innervated by α-motor neurons, which stimulate its fibres to contract. The cell bodies of α-motor neurons are located in either the ventral horn of the spinal cord (for limbs and trunk muscles) or in the motor nuclei of the brainstem (for head and face muscles).

skeletal muscles control involuntary body functions The functional unit of a skeletal muscle fiber is the sarcomere, a highly organized arrangement of the contractile myofilaments actin (thin filament) and myosin … The sarcomere is the contractile unit of a muscle fiber and the smallest functional unit of muscle. A sarcomere is the region of a myofibril between two successive Z discs; it primarily consists of thin and thick myofilaments. Skeletal muscle, like cardiac, is organized into repeating units of contractile proteins that are known as sarcomeres. This chapter describes the general features of this structural organization as Details of both the fine structure and contractile physiology of skeletal muscle fibers are presented in Chapter 5. Skeletal muscle fibers are not all homogeneous in either structure or function. Functionally, the speed of their contraction allows them to be divided into two main categories— fast and slow.
