ForearmThe forearm is the region of the upper limb between the elbow and the wrist. The term forearm is used in anatomy to distinguish it from the arm, a word which is used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm. It is homologous to the region of the leg that lies between the knee and the ankle joints, the crus.
Radial tuberosityBeneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity, or bicipital tuberosity; its surface is divided into: a posterior, rough portion, for the insertion of the tendon of the biceps brachii.an anterior, smooth portion, on which a bursa is interposed between the tendon and the bone.Ligaments that support the elbow joint also attach to the radial tuberosity.
Coronoid process of the ulnaThe coronoid process of the ulna is a triangular process projecting forward from the anterior proximal portion of the ulna. StructureIts base is continuous with the body of the bone, and of considerable strength. Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus. Its upper surface is smooth, convex, and forms the lower part of the semilunar notch.
Tuberosity of the ulnaThe tuberosity of the ulna is a rough eminence on the proximal end of the ulna. It occurs at the junction of the antero-inferior surface of the coronoid process with the front of the body. It provides an insertion point to a tendon of the brachialis (the oblique cord of the brachialis is attached to the lateral border).
RadiusIn classical geometry, a radius (pl.: radii or radiuses) of a circle or sphere is any of the line segments from its center to its perimeter (circle) or surface (sphere), and, in more modern usage, it is also their length. The radius of a regular polygon is the line segment or distance from its center to any of its vertices. The name comes from the Latinradius, meaning ray but also the spoke of a chariot wheel.
CadaverA cadaver, often known as a corpse, is a deadhuman body. Cadavers are used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being. Students in medical school study and dissect cadavers as a part of their education. Others who study cadavers include archaeologists and arts students.
Interosseous membrane of forearmThe interosseous membrane of the forearm (rarely middle or intermediate radioulnar joint) is a fibrous sheet that connects the interosseous margins of the radius and the ulna. It is the main part of the radio-ulnar syndesmosis, a fibrous joint between the two bones.
LigamentA ligament is a type of fibrous connective tissue in the body that connects bones to other bones. It also connects flight feathers to bones, in dinosaurs and birds. All 30,000 species of amniotes (land animals with internal bones) have ligaments. It is also known as articular ligament, articular larua, fibrous ligament, or true ligament. Comparative anatomyLigaments are similar to tendons and fasciae as they are all made of connective tissue.
Anatomical terms of locationStandard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes.
ElbowThe elbow is the region between the upper arm and the forearm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus.
Josias WeitbrechtJosias Weitbrecht (Russian: Иосия Вейтбрехт, born 6 November 1702 in Schorndorf, died 28 February 1747 in St. Petersburg) was a German professor of medicine and anatomy in the Russian Empire. Life and careerAfter his studies at the University of Tübingen initially Josias Weitbrecht acquired the academic degree for a magister of philosophy.UlnaThe ulna or ulnar bone (pl.: ulnae or ulnas) is a long bone in the forearm stretching from the elbow to the wrist. It is on the same side of the forearm as the little finger, running parallel to the radius, the forearm's other long bone. Longer and thinner than the radius, the ulna is considered to be the smaller long bone of the lower arm. The corresponding bone in the lower leg is the fibula.*As an Amazon Associate I earn from qualifying purchases.
