Multiple choice evs bones joints in the human body our skeletal system and the skin joints

Joint found between the edges of first metacarpal and carpal(trapezium) is?

  1. Hinge

  2. Condyloid

  3. Gliding

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A hinge joint allows movement primarily on one plane. A hinge joint spool like the surface of one bone fits into the concave surface of another love.

Articulation between the occipital condyls of skull and atlas vertebra also forms a huge joint.

Example of hinge joint is

  1. Elbow joint

  2. Ankle joint

  3. Interphalangeal joint

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The hinge joint is a synovial joint, which permits uniaxial movement of bone about one axis of rotation. In hinge joint, convex surface of one bone fits into concave surface of another. The movements possible are flexion and extension. Example of hinge joints are elbow, interphalangeal joint, knee and ankle joints.

Articulation of ulna with humerus at the elbow joint is _________ joint.

  1. Hinge

  2. Pivotal

  3. Gliding

  4. Ball and socket
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Answer:
1.The elbow joint is a synovial hinge joint with two articulations.
2.The trochlea of the humerus articulates with the trochlear notch of the ulna, and the capitulum of the humerus articulates with the head of the radius.
So correct answer is option A.Hinge joint.

A Correct answer
Explanation

Saddle joint is a type of synovial joint in humans in which opposing articular surfaces with both concave and convex surfaces fit into one another. Example of saddle joint is carpometacarpal joint of thumb.

Hinge joint is present between

  1. Femur and ulna

  2. Humerus and ulna

  3. Femur and pectoral girdle

  4. Femur and pelvic girdle
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Synovial joints are characterised by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. Such an arrangement allows considerable movement. These joints help in locomotion and many other movements. Common examples of synovial joints are ball and socket joint (between the humerus and pectoral girdle) and hinge joint (knee and elbow joints).

Fabellae bones are associated with

  1. Elbow joint

  2. Knee joint

  3. Neck joint

  4. Angular joint
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The fabella is a fibrocartilaginous or ossified sesamoid bone of the knee, classically located within the tendon of the lateral head of the gastrocnemius muscle, behind the lateral condyle of the femur.

Joint between atlas and axis is

  1. Pivot joint

  2. Saddle Joint

  3. Angular joint

  4. Hinge joint
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Joint between atlas and axis vertebrae is an example of pivot joint. It is a type of synovial joint. This joint is characterised with central bony pivot surrounded by collar of bone and ligament. This type of joint permits supination, rotation and pronation types of movements. Examples are proximal radioulnar joint and atlanto-axial joints.

Pivot joint occurs at

  1. The hip and shoulder joint

  2. Between the atlas and the odontoid process of axis

  3. Sternoclavicular joint

  4. Temporomandibular joint
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

According to functional classification, joints may be immovable (synarthroses), slightly movable (amphiarthroses) and freely movable (diarthrosis). According to structure, joints can be classified into fibrous, cartilaginous and synovial.
The pivot joint is a synovial joint, which permits the movement of bone about one axis of rotation. In pivot, the joint central bony pivot of one bone is surrounded by a collar of bone and ligaments. The types of movement possible are rotation, pronation, supination. An example of pivot joints is proximal radioulnar and atlantoaxial joints.

Which one is a ball and socket joint?

  1. Knee joint

  2. Elbow joint

  3. Humerus and pectoral girdle

  4. Skull and atlas
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ball and socket is a type of synovial joint in which globe-like the head of one bone fits into the cup-like concavity of another bone. It permits flexion, extension, internal rotation, lateral rotation, abduction, adduction and circumduction type of movements. 

Examples of ball and socket joints are shoulder and hip joint. In shoulders, each half of pectoral girdle consists of a clavicle and a scapula. The scapula is a large triangular flat bone situated in the dorsal part of the thorax between the second and the seventh ribs. The dorsal, flat, a triangular body of scapula has a slightly elevated ridge, called as the spine which projects as a flat, expanded process called the acromion. The clavicle articulates with this. Below the acromion is a depression called as the glenoid cavity, which articulates with the head of the humerus to form the shoulder joint.
