Ligaments.—The liver is connected to the under surface of the diaphragm and to the anterior wall of the abdomen by five ligaments; four of these—the falciform‚ the coronary‚ and the two lateral—are peritoneal folds; the fifth‚ the round ligament‚is a fibrous cord‚ the obliterated umbilical vein. The liver is also attached to the lesser curvature of the stomach by the hepatogastric and to the duodenum by the hepatoduodenal ligament (see page 1157). 17 The falciform ligament (ligamentum falciforme

function of an intervertebral disc? They absorb shocks and help equalize pressure between the vertebrae when the body moves 7) Describe the structure of a synovial joint. Two bones are held together by a joint capsule composed of two layers. Ligaments help reinforce the capsule. The cavity between the bones are filled with a viscous fluid called synovial fluid. 8) What is the function of the synovial joint? Allow free movements 9) Name six types of synovial joints and describe the structure

sutures ossify and fuse 1. Called Synostoses 2. Syndesmoses 1. Bones connected by ligaments (bands of fibrous tissue) 2. Fiber length varies so movement varies‚ i.e.‚ 1. Little to no movement at distal tibiofibular joint 2. Large amount of movement at interosseous membrane connecting radius and ulna 3. Gomphoses 1. Peg-in-socket joints of teeth in alveolar sockets 2. Fibrous connection is the periodontal ligament 5. Cartilaginous Joints 1. Bones united by cartilage 2. No joint cavity 3

Differentiate between tendons‚ ligaments and joints. - A tendon is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. - A joint is the location at which two or more bones make contact. - A ligament is a short band of tough fibrous dense regular connective tissue composed mainly of long‚ stringy collagen fibers. 5.

Fingers Injury : Sprain Normally sprain is a result of forced motion at a joint that stresses the supporting ligaments‚ causing varying degrees of damage. The forced motion usually hyperextension and lateral motion which is the lateral motion means stresses the collateral ligament and hyperextension means stresses the anterior capsule. There were several of symptoms of sprain injuries such as tenderness at the site of injury‚ increasing in pain on reproduction of the stress that caused the

dislocation happens when power or heavy amount of weight is put on a ligament‚ resulting the ends of two connected bones to detach. Ligaments are flexible bands of fibrous tissue that attach numerous bones and cartilage. Ligaments also bore the bones in a joint together. Tensions on joint ligament can consequent to dislocation of the joint. The hip and shoulder joints‚ for example‚ are called "ball and socket" joints. Extreme force on the ligaments in these joints can affect the ball to slightly or wholly

articulation with another bone and partially by a ligament . The bone rotates within this ring. Since the rotation is around a single axis‚ pivot joints are functionally classified as a uniaxial diarthrosis type of joint. An example of a pivot joint is the atlantoaxial joint‚ found between the C1 (atlas) and C2 (axis) vertebrae. Here‚ the upward projecting dens of the axis articulates with the inner aspect of the atlas‚ where it is held in place by a ligament. Rotation at this joint allows you to turn your

The fibrous connection is the periodontal ligaments. o Most fibrous joints are immovable o Sutures have very short CT fibers o In syndesmosis the bones are connected by a ligament A few notes about cartilaginous joints: o Epiphyseal plates are temporary and become synostoses o Symphyses are designed for strength with flexibility o Fibrocartilage is compressible

vertebrae. In between the bones there are joints that connect these together. A ligament connects bone to support joints. Muscles work by the fibers they contain contracting; this makes the muscle shorten. When the muscle shortens it pulls on the tendon and then on the bone to which it is attached. Muscles are connected to bones by tendons. Bones in limbs are covered with tissue. Not moving an individual correctly can cause ligaments to sprain. This is why individuals must never be dragged when being moved
