Question

What is Synovial Fluid

Answer 1

Synovial fluid is a viscous solution found in the cavities of synovial joints. The principal role of synovial fluid is to reduce friction between the articular cartilages of synovial joints during movement.

Answer 2

In a Synovial joint, the ends of bones are encased in smooth cartilage. Together, they are protected by a joint capsule lined with a synovial membrane that produces synovial fluid. The capsule and fluid protect the cartilage, muscles, and connective tissues.

Answer 3

Fibrous Joints Cartilaginous Joints Synovial Joints Ball and Socket Joints Pivotal Joint Hinge Joints Saddle Joints Condyloid Joints

Answer 4

Cartilaginous Joints are a type of joint where the bones are entirely joined by cartilage. Example - Sternocostal joint

Answer 5

Synovial Joint is the type of joint found between bones that move against each other such as the joints of the limbs, such as EG.. Shoulder, Hip, elbow and Knee, Characteristically it has a joint cavity filled with fluid Example - Shoulder, Knee, Elbow, Shoulder

Answer 6

Ball and socket - these types of joint can be found at the shoulder and hip and allow movement in almost every direction. A ball and socket joint is made up of a round end of one bone that fits into a small cup-like area of another bone. Example - Upper arm and shoulder, upper leg and hip

Answer 7

Pivot Joins are freely moveable joints that allow rotatory movement of bones, around a single axis. Example - in the neck

Answer 8

A hinge joint is a type of synovial joint . the hinge joint is made up of two or more bones with articular surfaces that are covered by cartilage and lubricated by synovial fluid Example - elbow, knee.

Answer 9

Synovial Joint is a type of synovial joint that supports a wide range of movement. saddle joint scan move up and down and back and forth. Example - whilst there are 300 joints in the body there are only 3 saddle joints... Shoulder, Thumb, Ear

Answer 10

Condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction and adduction Example - the wrist

Answer 11

Extension Flexion Abduction Adduction Rotation Plantar Flexion Dorsiflexion

Answer 12

Bending a joint. occurs when the angle of a joint decreases. Example - whilst performing a bicep curl

Answer 13

Straightening a joint. this occurs when the angle of a joint increases. Example - At the elbow when putting a shot (in shotput)

Answer 14

Movement away from the midline of the body. Example - Occurs at the hip and the shoulder joints during a star jump movement

Answer 15

This is where the limb moves in a circular movement around a fixed joint towards or away from the midline of the body. Example - Occurs in the hip while performing a drive shot in golf

Answer 16

Pointing the toes. Occurs only at the ankle Example - Pointing the toes in ballet

Answer 17

The foot moves towards the shin as if you are pulling your toes up. this movement only occurs at the ankle
