Which muscle allows a person to run, climb stairs and rise from a sitting position? Structure of Skeletal Muscle Don't miss this! A skeletal muscle is an organ of the muscular system. It is composed of skeletal muscle tissue, nervous tissue, blood, and other connective tissues. Layers of fibrous connective tissue called fascia separate an individual skeletal muscle from adjacent muscles and hold it in position. This connective tissue surrounds each muscle and may project beyond its end to form a cordlike tendon. Fibers in a tendon may intertwine with those in a bone's periosteum, attaching the muscle to the bone. In other cases, the connective tissue forms broad fibrous sheets called aponeuroses, which may attach to bone or to the coverings of adjacent muscles. The layer of connective tissue that "n closely surrounds a skeletal muscle is called e Other layers of Thick connective tissue, called perimysium, extend inward form the epimysium and separate the muscle tissue into small compartments. These compartments contain bundles of skeletal muscle fibers called fascicles (fasciculi). Each muscle fiber within a fascicle lies within a layer of connective tissue in the form of a thin covering called endomysium. Layers of connective tissue, therefore, enclose and separate all parts of a skeletal muscle. This organization allows the parts to move somewhat independently. Many blood vessels and nerves pass through these layers. A skeletal muscle is composed of a variety of tissues, including layers of connective tissue. Fascia covers the surface of the muscle, epimysium lies beneath the fascia, and perimysium extends into the structure of the muscle where it separates muscle cells into fascicles. Endomysium separates individual muscle fibers. A skeletal muscle fiber is a singe cell that contracts in response to stimulation and then relaxes when the stimulation ends. Each skeletal muscle fiber is a thin, elongated cylinder with rounded ends, and it may extend the full length of the muscle Just beneath its cell membrane (or sarcolemma),the cytoplasm (or sarcoplasm) of the fiber has many small, oval nuclei and mitochondria. The sarcoplasm also contains many threadlike myofibrils that lie parallel to one another. Myofibrils play a fundamental role in muscle contraction. They consist of two kinds of protein filaments-thick ones composed of the protein myosin and thin ones mainly composed of the protein actin. The organization of these filaments produces the characteristic alternating light and dark striations, or bands of a skeletal muscle fiber.
Explanation / Answer
1)buccinator,frontalis
2)levator labii superioris
3)orbicularis occuli
4)orbicularis oris
5)zygomaticus major
6)superior rectus
7)inferior rectus, lateral rectus.
8)medial rectus
9)The masseter muscle is the main muscle used for chewing .The action of the muscle during bilateral contraction of the entire muscle is to elevate the mandible, raising the lower jaw. Elevation of the mandible occurs during the closing of the jaws. The masseter parallels the medial pterygoid muscle, but it is stronger and superficial fibres can cause protrusion.
The genioglossus is the major muscleresponsible for protruding (or sticking out) the tongue.
The hyoglossus, thin and quadrilateral, arises from the side of the body and from the whole length of the greater cornu of the hyoid bone, and passes almost vertically upward to enter the side of the tongue, between the styloglossus and the inferior longitudinal muscle of the tongue.
10)trapezius
11)a splenius capitis/cervicis
12)trapezius
levator scapulae
13)Deltoid muscle
14)Pectoral Major & latissimus dorsi
15) rhomboids and middle trapezius.
16)Rectus Abdominis,Rectus Femoris.
17). The diaphragm , the intercostal muscles,Accessorymuscles.
18)Levator Ani
19)Longissimus Thoracis
20)the biceps, also biceps brachii is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. Both heads arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.
21)The flexor digitorum profundus is a muscle in the forearm that flexes the finger.it is considered an extrinsic hand muscle because it acts on the hand while its muscle belly is located in the forearm.
22)The flexor pollicis longus is a muscle in the forearm and hand that flexes the thumb. It lies in the same plane as the flexor digitorum profundus.
23)The intrinsic muscles
24)radialis muscles
25)ACE muscles
26)The extrinsic muscles arise from the anterior, posterior and lateral compartments of the leg. They are mainly responsible for actions such as eversion, inversion, plantarflexion and dorsiflexion of the foot.
27)gluteal group: gluteus maximus
