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

Choose the correct answer from the alternatives given.
Equilibrium and activities of the muscles and Joints are monitored by

  1. proprioceptors

  2. tactile receptors

  3. receptory receptors

  4. gustatory receptors
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

(A)Propioceptor responds to activities of muscles and joints.

(B)Tactile receptors responds to touch.
(C)Receptory receptors respond to the specific receptor.
(D)Gustatory receptors respond to taste.
So, the correct option is 'propioceptor'.

Axis is different from atlas in the

  1. Presence of odontoid process

  2. Presence of central cavity

  3. Absence of central cavity

  4. Presence of neural cavity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The axis has a bony peg called the odontoid process, which sticks up through the hole in the atlas. It is this special arrangement that allows the head to turn from side to side as far as it can.

True joint are

  1. Synchondroses

  2. Syndesmoses

  3. Synovial

  4. Ball and socket
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A joint in the human body is a connection between the tissues, cartilages and bones. These are classified structurally and functionally and of these, the synovial joint is one that is functionally freely movable. The pectoral girdle or the shoulder girdle which is synovial joint is made up of a set of bones, the clavicle and scapula that connects the arms to the axial skeleton on both sides. In fact, the shoulder girdle has five joints of which three are anatomical (true joint ) and two are physiological or false joints.

Which of the following pair is correctly matched?

  1. Cartilaginous joint - skull bones

  2. Hinge joint - between vertebrae

  3. Fibrous joint - between phalanges

  4. Gliding joint - between zygapophyses of the successive vertebrae
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • A gliding joint is a common type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces.
  • Gliding joints allow the bones to glide past one another in any direction along the plane of the joint — up and down, left and right, and diagonally. For example, between zygapophyses of the successive vertebrae.
  • Hence Gliding joint - between zygapophyses of the successive vertebrae are correctly matched.
  • So, the correct answer is 'Gliding joint - between zygapophyses of the successive vertebrae'.

When a joint allows restricted movement in one plane only, it is known as a

  1. Hinge joint

  2. Gliding joint

  3. Angular joint

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

The hinge joint is a joint in which a convex part of one bone fits into a concave part of another, allowing motion in only one plane. In hinge joint, the two bones open and close in one direction only (along one plane) like a door, such as a knee joint.

So, the correct answer is 'Hinge joint'

Example of pivot joint is

  1. Atlanto-axial joint

  2. Shoulder joint

  3. Hip joint

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

Pivot joint is a synovial joint, which permits uniaxial movement of bone about one axis of rotation. In pivot joint central bony pivot is surrounded by collar of bone and ligament. The movements possible are supination, pronation and rotation. Examples of pivot joints are proximal radioulnar joint and atlanto-axial joint.

A joint between humerus and radio Ulna is

  1. Ball and socket

  2. Pivot

  3. Gliding

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

The humerus and the radioulna together form the elbow which is the hinge joint. The distal end of the humerus articulates the proximal end of the radius and ulna. The humeroulnar joint is also a part of the elbow and is a hinge joint whereas the proximal radioulnar and the distal radioulnar is a pivot joint. Thus, the correct answer is option D.

The ball and socket joint is found in

  1. Skull

  2. Shoulder

  3. Knee

  4. Atlas and axis
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The ball and socket joint is the type of synovial joint present between the bones having structures like ball and socket. This joint is found in the shoulder joint. Head of the humur acts as the ball and the glenoid cavity of scapula acts as the socket.

Skull contains immovable joints called sutures. They are present in the skull bones.
The hinge joint is the type of synovial joint found in the knee which permits movement only in one plane.
The pivot joint is the type of joint found between atlas and axis.
So the correct option is B.
