Question

Where is the skeletal muscle located?

Answer 1

Cardiac, smooth, and skeletal muscle tissue are the three forms of muscle tissue. Cardiac muscle cells are found in the heart's walls, are striated, and are controlled involuntarily. Smooth muscle fibres, with the exception of the heart, are found in the walls of hollow visceral organs, are spindle-shaped, and are controlled involuntarily. Muscle fibres that are connected to the skeleton are known as skeletal muscle fibres. They have a striated appearance and are controlled by the user.

Complete answer:
Most Tendons are bundles of collagen fibres that connect skeletal muscles to bones.
Skeletal muscles are striated muscular tissue that is within the body's voluntary control.
The human body contains roughly 640 skeletal muscles. They can be classified into the following categories:
1. Frontalis, for example, is a type of head.
2. Neck muscles such as the sternocleidomastoid
3. Spinalis, for example, is a part of the torso.
4. Trapezius, for example, is a muscle in the upper limb.
5. Gluteus maximus, for example, is a muscle in the lower limbs.
Skeletal muscles, often known as muscles, are organs of the vertebrate muscular system that are primarily linked to the skeleton's bones through tendons. Skeletal muscle cells are substantially longer than those found in other types of muscle tissue, and are referred to as muscle fibres. A skeletal muscle's muscle tissue is striated, giving it a striped look due to the arrangement of sarcomeres.
Skeletal muscles are controlled by the somatic nervous system and are voluntary muscles. The two forms of muscle include striated cardiac muscle and smooth muscle, both of which are involuntary and controlled by the autonomic nervous system.
Multiple fascicles — bundles of muscle fibres – make up a skeletal muscle. Fascia is a sort of connective tissue layer that surrounds each individual fibre and muscle. Muscle fibres are created by the merging of developmental myoblasts, which results in long multinucleated cells, a process known as myogenesis.
The nuclei of these cells, known as myonuclei, are found on the inner of the cell membrane. To meet energy demands, muscle fibres include many mitochondria. Myofibrils are the building blocks of muscle fibres. Myofibrils are made up of actin and myosin filaments called myofilaments that are repeated in units called sarcomeres, which are the muscle fiber's basic functional and contractile units. Muscles are primarily driven by fat and carbohydrate oxidation, but anaerobic chemical processes, particularly in quick twitch fibres, are also utilised.
Adenosine triphosphate (ATP) molecules are produced as a result of these chemical events, which are needed to power the movement of the myosin heads.

Note:-
The human body has around 650 skeletal muscles, which account for about 40% of total body weight. The majority of muscles are found in bilateral pairs to service both sides of the body. Muscles are frequently classified as groups of muscles that collaborate to perform a task.
