Bundles of muscle cells are called fascicles. The fascicle is made of connective tissue which surrounds individual muscle cells.
The connective tissues surrounding the fascicles are called perimysium.

Muscles are composed of connective tissue and contractile cells. The connective tissues surrounding the entire muscle is the epimysium. Bundles of muscle cells are called fascicles.
The connective tissues surrounding the fascicles are called perimysium. The fascicle is made of connective tissue which surrounds individual muscle cells. Its main functions are to electrically insulate muscle.
As seen in the image below a muscle cell is a compact bundle of many myofibrils. Each myofibril is made of many sarcomeres bundled together and attached end-to-end. A specialized form of the endoplasmic reticulum known as the sarcoplasmic reticulum extends in and around these myofibril bundles.
The sarcoplasmic reticulum SR for short concentrates a chemical needed for the muscle. Practical 3 Learn with flashcards games and more for free. Draw the diagram of a muscle cell and a nerve cell.

Diagram of a muscle cell and a nerve cell. Prev Question. Skeletal muscle cells a striated muscle cell type form the muscle that we use to move and are compartmentalized into different muscle tissues around the body such as that of the biceps.
Skeletal muscles are attached to bones by tendons and can be as long as. The muscles of the human body can be categorized into a number of groups which include muscles relating to the head and neck muscles of the torso or trunk muscles of the upper limbs and muscles of the lower limbs. The human body has three different types of muscles.
Skeletal muscles smooth muscles cardiac muscles. Muscle cell diagram 661. This image displays Muscle cell diagram.
Skeletal muscle cells occur in the form of multinucleated fibers that can be up to several centimeters long. In the embryo a skeletal muscle fiber begins as a single cell called a myoblastIndividual myoblasts begin to fuse with one another forming elongated cells called myotubes in which dozens of nuclei are lined up in a central row Fig. A muscle cell is also known as a myocyte when referring to either a cardiac muscle cell or a smooth muscle cell as these are both small cells.
A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. Muscle cells develop from embryonic precursor cells called myoblasts. Myoblasts fuse to form multinucleated skeletal muscle cells known as syncytia in a process known as.
