Muscle is a contractile form of tissue. It is one of the four major tissue types, the other three being epithelium, connective tissue and nervous tissue. Muscle contraction is used to move parts of the body, as well as to move substances within the body. Muscle - Types. There are three general types of muscle: Cardiac muscle is a specialized kind of muscle found only within the heart. It cannot get tired and is "involuntary". Skeletal muscle or "voluntary muscle" is anchored by tendons ...

The gluteus maximus is the uppermost of the three muscles. It is the largest of the gluteal muscles and, by some definitions, is the most powerful muscle of the human body (see Muscle). It inserts at the iliotibial band and the gluteal tuberosity of the femur. Its action is to extend and outwardly rotate hip, and extend the trunk. Powerlifting exercises which are known to significantly strengthen the gluteus maximus include the squat and the deadlift. The leg press also uses the gluteus maximus. < ...

The anconeus muscle is a small muscle on the posterior surface of the elbow. There are suggestions that this muscle is embryologically the fourth head of the triceps brachii muscle. The limbs are derived from embryologically similar origins and since the lower limb muscle quadriceps femoris muscle has four heads, it would seem to make sense. ...

There are three general types of muscle: Cardiac muscle is a specialized kind of muscle found only within the heart. It cannot get tired and is "involuntary". Skeletal muscle or "voluntary muscle" is anchored by tendons to bone and is used to affect skeletal movement such as locomotion. It gets tired. Smooth muscle or "involuntary muscle" is found within structures such as the intestines, throat and blood vess ...

The cremaster muscle is a muscle which covers the testis. Its function is to raise and lower the scrotum in order to regulate the temperature of the testis and promote spermatogenesis. In a cool environment the cremaster draws the testis closer to the body preventing heat loss, while when it is warmer the cremaster relaxes allowing the testis to cool. The cremaster develops to its full extent only in males; i ...

The calf or sura is a pair of muscles -- the gastrocnemius and soleus -- at the back of the lower human leg. The calf muscle is connected to the foot through the Achilles tendon, which acts to plantar flex the foot. so it is used extensively in walking and running.

The Auriculares muscles are the three muscles surrounding the auricula or outer ear. The Auricularis anterior (Attrahens aurem), the smallest of the three, is thin and fan-shaped, and its fibers are pale and indistinct. It arises from the lateral edge of the galea aponeurotica, and its fibers converge to be inserted into a projection on the front of the helix. The Auricularis superior (Attolens aurem), the largest of the three, is also thin and fan-shaped. Its fibers arise from the galea aponeurotica, and converge to be inserted by a thin, flattened tendon i ...

The cricothyroid muscle attaches to the anterolateral aspect of the cricoid and the inferior cornu and lower lamina of the thyroid cartilage, tilting the thyroid forwards and lengthening the vocal cords. It's the only laryngeal muscle supplied by the external laryngeal nerve (rather than the recurrent laryngeal nerve).

Bulbospongiosus is one of the superficial muscles of the perineum. It has a slightly different origin, insertion and function in males and females. In males, it covers the bulb of the penis. In females, it covers the vestibular bulb. In both sexes, it is innervated by the deep/muscular branch of the perineal nerve, which is a branch of the pudendal nerve. In males it contributes to erection, ejaculation, and the feelings of orgasm. In females it closes the vagina and contributes to the feeli ...

Cardiac muscle is a type of striated muscle found within the heart. Its function is to "pump" blood through the circulatory system by contracting. Unlike skeletal muscle, which contracts in response to nerve stimulation, and like smooth muscle, cardiac muscle is myogenic, meaning that it stimulates its own contraction without a requisite electrical impulse. A single cardiac muscle cell, if left without input, will contract rhythmically at a steady rate; if two cardiac muscle cells are in contact, whichever one contracts first w ...

The Adductor longus muscle is a muscle of the human body. It is a part of the adductor group of the thigh, that as the name suggests adduct the thigh. It originates on the pubic body just below the pubic crest and inserts into the middle third of linea aspera. Its nerve supply is the obturator nerve, branch of anterior division L2, L3, and L4.

Muscle weakness (or "lack of strength") is the inability to exert force with ones muscles to the degree that would be expected given the individual's general physical fitness. A test of strength is often used during a diagnosis of a muscular disorder before the etiology can be identified. The term subsumes two other more specific terms, true weakness and perceived weakness. True weakness (or "objective weakness") describes a condition where the instantaneous force exerted by the muscles is less ...

In human anatomy, the biceps brachii is a muscle on the upper arm that acts to flex the elbow. Contrary to popular belief, the main flexor of the forearm is not the bicep, but the brachialis muscle, which is deep to the bicep. The bicep is arguably the best known muscle, as it lies fairly superficially, and is often well-defined even in non-athletes. It is given the name biceps because it has two heads, and brachii comes from the Latin word for arm. The muscle is popular amongst bodybuilders, and can grow quite large through weight lifting. The world ...

The ciliary body is the part of the eye containing the ciliary muscle and ciliary processes. There are two sets of ciliary muscles in the eye. They are near the front of the eye, above and below the lens. They are attached to the lens by connective tissue called zonular fibers, and are responsible for shaping the lens to focus light on the retina. When the ciliary muscle relaxes, it flattens the lens which generally improves the focus for farther objects. When it contracts, the lens becomes more convex which generally i ...
