Information about Symphysis

Cartilage is a type of dense connective tissue. It is composed of collagen fibers and/or elastin fibers, and can supply smooth surfaces for the movement of articulating bones.

The pubic symphysis is the midline cartilaginous joint uniting the superior rami of the left and right pubic bones (pubis). It is located anterior to the urinary bladder and superior to the external genitalia; for females it is above the vulva and for males it is above the penis.

skull is a bony structure found in many animals which serves as the general framework for the head. The skull supports the structures of the face and protects the head against injury.

The skull can be subdivided into two parts: the cranium and the mandible.

mandible (from Latin mandibūla, "jawbone") or inferior maxillary bone is, together with the maxilla, the largest and strongest bone of the face . It forms the lower jaw and holds the lower teeth in place.

The sacrococcygeal symphysis (sacrococcygeal articulation, articulation of the sacrum and coccyx) is an amphiarthrodial joint, formed between the oval surface at the apex of the sacrum, and the base of the coccyx.

Amphiarthroses is a type of continous joint. In Amphiarthroses (slightly movable articulations), the contiguous bony surfaces are either:

• symphysis: connected by broad flattened disks of fibrocartilage, of a more or less complex structure, as in the articulations

Gomphosis is a synarthrosis (joint) that binds the teeth to bony sockets in the maxillary bone and mandible. The fibrous connection between a tooth and its socket is a periodontal ligament.

Synovial joints (or diarthroses, or diarthroidal joints) are the most common and most moveable type of joints in the body. As with all other joints in the body, synovial joints achieve movement at the point of contact of the articulating bones.

In the hinge joint (ginglymus), the articular surfaces are moulded to each other in such a manner as to permit motion only in one plane, forward and backward, the extent of motion at the same time being considerable.

Pivot joint (trochoid joint, rotary joint): Where the movement is limited to rotation, the joint is formed by a pivot-like process turning within a ring, or a ring on a pivot, the ring being formed partly of bone, partly of ligament.

In a condyloid joint (condyloid articulation, ellipsoidal joint) an ovoid articular surface, or condyle, is received into an elliptical cavity in such a manner as to permit of flexion, extension, adduction, abduction, and circumduction, but no axial rotation.

In a saddle joint (sellar joint, articulation by reciprocal reception) the opposing surfaces are reciprocally concave-convex.

The movements are the same as in a condyloid joint; that is to say, flexion, extension, adduction, abduction, and circumduction are

ball and socket joint (enarthrosis, spheroidal joint) is a joint in which the distal bone is capable of motion around an indefinite number of axes, which have one common center.

A gliding joint (arthrodial joint, plane articulation) is a synovial joint which admits of only gliding movement.

Example

It is the form present in:

• the joints between the articular processes of the vertebrae,

Kinesiology is the scientific study of the anatomy, physiology, and mechanics of body movement, especially in humans. ^[1] The word kinesiology is derived the Greek "kinesis" (motion) + the suffix -ology or -logy from the greek "logos" or "logia"(meaning a field of study).

hyper- is sometimes added to emphasize movement beyond the normal position, such as in hyperflexion or hyperextension. Such movements can put significant stress on the joints involved.

Agonist is a kind of muscle that causes movement to occur. It creates the normal range of movement in a joint by contracting. Agonists are also referred to as "prime movers" since they are the muscles that are primarily responsible for generating movement.

An antagonist is a kind of muscle that acts in opposition to the movement generated by the agonist and is responsible for returning a limb to its initial position.

Antagonistic pairs in houses

These antagonistic muscles are found in pairs called antagonistic pairs.

flexion is a position that is made possible by the joint angle decreasing. The skeletal (bones, cartilage, and ligaments) and muscular (muscles and tendons) systems work together to move the joint into a "flexed" position.
..... Click the link for more information.

Extension is a movement of a joint. For example, extension is produced by extending the flexed elbow. The arm is now straight; it has been extended. If the head is tilted all the way back, it is said to be extended.

The movement in the opposite directions is called flexion.

Adduction is a movement which brings a limb - arm or leg - closer to the sagittal plane of the body. It is opposed to abduction.

This term is also used when one speaks about the operation of the muscle in anatomy or musculature.

Abduction, in functional anatomy, is a movement which draws a limb away from the median (Sagittal) plane of the body. It is thus opposed to adduction.

In anatomy, internal rotation (also known as medial rotation) is rotation towards the center of the body.

The muscles of internal rotation include:

• of arm/humerus at shoulder^[1]

External rotation (or lateral rotation) is rotation away from the center of the body.

The muscles of external rotation include:

• of arm/humerus at shoulder^[1]

Supination is the rotation of the forearm so that the palm faces anteriorly, or palm facing up (when the arms are unbent and at the sides).

The hand is supine (facing anteriorly) in the anatomical position.

Pronation is an anatomical term to describe a rotation movement^[1]. Such movement can occur in the forearm (at the radioulnar joint) and the foot (at the subtalar and talocalcaneonavicular joints)<ref name="Kendall et al." />^[2].

Plantarflexion is the movement which increases the angle between the foot and the leg, as when depressing an automobile pedal. The word "Plantar" translates as "toward the sole" ("Planta").

The movement in the opposite direction is Dorsiflexion.

Dorsiflexion is the movement which decreases the angle between the foot and the leg. The movement moving in opposite directions is called Plantarflexion.

The range of motion for dorsiflexion is indicated in the literature as 20° to 30°.
