Question

Sarcolemma is found over
A. Heart
B. Skeletal muscle fibers
C. Nerve fiber
D. Heart muscle

Answer 1

Hint: Hint: Sarcolemma, is a membrane found over particular tissue in the human body. The major function of it is to provide protection like any other tissue membranes. It also helps in the conduction of various impulses throughout the length of the tissue.

Complete step by step answer:Sarcolemma is the membrane found over skeletal muscle fibers. In the striated muscle fiber cell, the cell membrane is known as the sarcolemma. As any other cell membrane, they also possess a lipid bilayer structure. The membrane consists of collagen fibers and also certain specialized proteins. Considering the other given options:
Heart is one of the most vital organs in the body. It helps in pumping of blood to various target organs. The outer covering present over the heart is known as the Pericardium. It is double layered. This helps in protecting the heart from any external shock.
Nerve fibers are also known as neurons. These cells are involved in conduction of impulses throughout the body. The outer cell membrane of a neuron is known as the plasma membrane. Heart muscles are also known as cardiac muscles. It helps in conduction of impulses.
Thus, from the given options, the most appropriate one is B, that is, sarcolemma is found over skeletal muscle fibers.

Note:The skeletal muscle fibers are found in close association with the bones, they are connected by means of structures known as tendons. These muscles are controlled by the voluntary or the somatic nervous system. These muscle fibers are present together in the form of bundles known as the fascia.
