articulations flashcards

Flashcards about the skeletal system articulations lecture.

These joints have no joint cavity and exhibit little or no movement. What are they?

Fibrous and cartilaginous joints

These specialized joints consist of pegs that fit into sockets and are held together by regular collagenous connective tissue. What are they?

Gomphoses

The joint found in between the intervertebral discs is a .

Symphysis

This extension of the synovial membrane extends as a pocket to provide a cushion between structures that would rub against each other: What is it?

Bursa

Hinge joints are found between all of the following bones EXCEPT: femur and tibia, phalanges, humerus and ulna and radius, or atlas and axis?

Atlas and axis

Flexion at the knee moves the leg in an anterior direction. True/False

False

This movement consists of moving a structure in a gliding motion in an anterior direction. What is it?

Protraction

Abduction of the fingers will do this: spread them apart, bring them together, bend them, or straighten them?

Spread them apart

This movement of the forearm will allow you to hold a bowl of soup in your hands. What is it?

Supination

These movements will move the right upper limb from the anatomical position to touch the right side of the head with the fingertips. What are they?

Shoulder abduction/ elbow flexion or shoulder flexion/ elbow flexion

The shoulder joint is a ball and socket joint between the head of the humerus and glenoid cavity (fossa) of the scapula. True/False

True

These movements are possible at the temperomandibular joint EXCPET: depression, protraction, rotation, or excursion?

Rotation

The following describe the elbow joint: hinge, can produce rotation, olecranon bursa covers olecranon process, surrounded by joint capsule, or all of these?

All of these

This structure helps to stabilize the shoulder joint: rotator cuff muscles, cruciate ligaments, articular disk, or medial and lateral collateral ligaments?

Rotator cuff muscles

This statement about a shoulder dislocation is true: most common dislocated joint, usually occurs inferior to the axilla, axillary nerve can be damaged, or all are true?

All are true or B and C only

The hip joint is an ellipsoid (condyloid) joint, which is a modified ball and socket joint. True/False

False

The hip joint is formed by these bone features: pubic symphysis and lesser trochanter, femoral head and acetabulum, greater trochanter and acetabulum, or femoral head and ischial tuberosity?

Femoral head and acetabulum

These movements are produced at the knee joint: flexion, extension, abduction, adduction?

Flexion and extension

A sprained ankle is most often a result of this: crushed talus, torn calcaneofibular ligament, fracture of fibular lateral malleolus, or fracture of tibial medial malleolus?

Torn calcaneofibular ligament

This ligament can be torn when the knee receives a blow to the anterior surface or if it is hyperextended: tibial collateral ligament, fibular collateral ligament, anterior cruciate ligament, or posterior cruciate ligament?

Anterior cruciate ligament

This synovial joint is the most freely movable: hinge, saddle, gliding, or ball and socket?

Ball and socket

This kind of movement occurs in ballet when dancers point their toes: dorsiflexion, plantarflexion, inversion, or eversion?

Plantarflexion

In some elderly, when a suture becomes ossified, two bones grow together to become a single bone. This is called _.

Synostosis

The ulnar collateral and radial collateral ligament are found in this joint: knee, shoulder, hip, or elbow?

Elbow

This condition is a severe form of arthritis that is an autoimmune attack against the joint tissue: osteoarthritis (degenerative), rheumatoid arthritis, gout, or hemophilic arthritis?

Rheumatoid arthritis

These are all results of the aging of joints except: production decline of synovial fluid, production decline of new matrix, ligaments and tendons stretch, or tissue repair slows?

Production decline of new matrix. Ligaments and tendons stretch
