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 ...

Muscle spindles are found within the fleshy portions of muscles, embedded in so-called extrafusal muscle fibers. They are composed of 3-10 intrafusal muscle fibers, of which there are two types, nuclear bag fibers and nuclear chain fibers and the axons of sensory neurons. Axons of motoneurons also terminate in muscle spindles; they make synapses at either or both of the ends of the intrafusal muscle fibers and regulate spindle sensitivity. Muscle spindles are encapsulated by connective tissue, and are aligned parallel to extrafusal muscle fibers, unlike Golgi te ...

In the anatomy of mammals, the urinary bladder is the organ that collects urine excreted by the kidneys prior to disposal by urination. Urine enters the bladder via the ureters and exits via the urethra. Urinary bladder - Anatomy. The urinary bladder is a hollow, muscular and distensible organ that sits on the pelvic floor (superior to the prostate in males). On its anterior border lies the pubic symphysis and, on its posterior border, the vagina (in females) and rectum (in males). The urinary bladd ...

The coronary circulation consists of the blood vessels that supply blood to, and remove blood from, the heart. The vessels that supply blood high in oxygen to the heart are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart are known as cardiac veins. The coronary arteries that run on the surface of the heart are called epicardial coronary arteries. These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart mu ...

The tongue is the large bundle of muscles on the floor of the mouth that manipulates food for chewing and swallowing. It is one of the organs of taste. Much of the surface of the tongue is covered in taste buds. The tongue assists in forming the sounds of speech. The word tongue can be used as a synonym for language, e.g., as in the phrase mother tongue. It is also examined and observed diagnostically in traditional Chinese medicine. The tongue is made mainly of skeletal muscle and attached to the hyoid bone, mandible an ...

Biomechanics is the research and analysis of the mechanics of living organisms. Aristoteles might be considered the first biomechanicist. He wrote the first book called "De Motu Animalium" - On the Movement of Animals. He not only saw animals' bodies as mechanical systems, but pursued such questions as the physiological difference between imagining performing an action and actually doing it. (Read more about the history of Biomechanics in A Genealogy of Biomechanics.) The research and analysis can be carried forth on multiple levels, ...

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 ...

In human anatomy, the cephalic vein is a superficial vein of the upper limb. It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle. Superiorly the cephalic vein passes between the deltoid and pectoralis major muscles and through the deltopectoral triangle, where it empties into the ...

In human anatomy, the knee is the leg joint connecting the femur and the tibia. Knee - Human anatomy. The knee is a complex, compound, condyloid variety of a synovial joint. It actually comprises two separate joints. The femoro-patellar joint consists of the patella, or "kneecap", a so-called "sesamoid bone" which sits within the tendon of the anterior thigh muscles, and the patellar groove on the front of the femur through which it slides. The femoro-tibial joint links the femur, or thigh bone, with the ti ...

In anatomy, the urethra is a tube which connects the urinary bladder to the outside of the body. The urethra has an excretory function in both sexes, to pass urine to the outside, and also a reproductive function in the male, as a passage for sperm. The external urethral sphincter is a smooth muscle that allows voluntary control over urination. Urethra - Anatomy. Men have a longer urethra than women. This means that women tend to be more susceptible to infections of the bladder (cystitis) and the uri ...

In human anatomy, the axillary vein is a large blood vessel that conveys blood from the lateral aspect of the thorax, axilla (armpit) and upper limb toward the heart. Its origin is at the lower margin of the teres major muscle and a continuation of the brachial vein. Its tributaries include the basilic vein and cephalic vein, which are both superficial veins. It terminates at the lateral margin of the first rib, at which it becomes the subclavian vein. It is accompanied along its cour ...

The vas deferens, also called ductus deferens, (Latin: "carrying-away vessel") is part of the human male anatomy. There are two of them; they are muscular tubes (surrounded by smooth muscle) connecting the left and right epididymis to the ejaculatory ducts in order to move sperm. Each tube is about 30 centimeters long. During ejaculation the wall of the vas deferens thickens and thins itself, thus propelling the sperm forward. The sperm are transferred from the vas deferens into the urethra, collecting fluids from the male accessory sex glands en route. Vasectomy is a method of contrace ...
