  3. Hemarthrosis

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

A synarthrosis is a fixed joint between bones connected by fibrous tissue. A suture is a type of fibrous joint that is only found in the skull. The sutures between bones of the skull is an example of synarthrosis. So, the correct answer is 'Synarthrosis'.

C Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • A suture is a type of fibrous joint that is only found in the skull. Parietals are the bones present in the skull.
  • Sutural joints are present between parietals (bones of the skull)of the skull.
  • So, the correct answer is 'Parietals of the skull'.

  1. First vertebra is axis which articulates with occipital condyles.

  2. Parietal bone and temporal bone of skull are jointed by fibrous joint.
  3. 9$^{th}$ and 10$^{th}$ pairs of ribs are called floating ribs.

  4. Glenoid cavity is depression to which thigh bone articulates.

B Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • A suture is a type of fibrous joint that is only found in the skull. The skull bones are joined by the sutures.
  • Parietal bone and temporal bone are skull bones.
  • Hence parietal bone and temporal bone of skull are joined by fibrous joint.
  • So, the correct answer is 'Parietal bone and temporal bone of skull are joined by fibrous joint'.

The joint between the human skull bones is

  1. Hinge joint

  2. Immovable joint

  3. Cartilaginous joint

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

A suture is a type of fibrous joint that is only found in the skull. The bones are bound together by Sharpey's fibers. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull which is immovable.

So, the correct option is 'Immovable joint'.

Which one of the following is the correct description of a certain part of a normal human skeleton ?

  1. Parietal bone and the temporal bone of the skull are joined by fibrous joint.

  2. First vertebra is axis which articulates with the occipital condyles.

  3. The 9th and 10th pairs of ribs are.called the floating ribs.

  4. Glenoid cavity is a depression to which the thigh bone articulates.

A Correct answer
Explanation

Fibrous joints are connected by dense connective tissue consisting mainly of collagen, also called immovable joints.

So, the correct option is 'Parietal bone and the temporal bone of the skull are joined by fibrous joint.'.

Sutures are

  1. Movable joints

  2. Cracks in the skull bone

  3. Immovable joints

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A suture is a type of fibrous joint, which only occurs in the skull (or cranium). They are bound together by Sharpey's fibres. These joints are synarthroses. A small movement is permitted at sutures, which contributes to the compliance and elasticity of the skull.

If a ligament is cut or damaged the joint becomes

  1. Freely movable

  2. Immovable

  3. Unaffected

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

The connective tissues which are found around joints are the ligaments and this help to stabilise the joint, maximise its strength and prevent any excess movement of the joints. The ligaments are attached to both sides of the bones and any tear or injury to the ligaments tends to make the joints unstable. So, the correct answer is option D.

Which one of the following membranes secretes a watery fluid that lubricates and cushions the joint ?

  1. Tendons

  2. Ligaments

  3. Cartilage

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

The synovial membrane is the membrane that lines the articular surfaces of the bones of the synovial joint. Its secretes a watery fluid that lubricates and cushions the joint. It reduces the friction during movement.

Tendon is a cord of strong fibrous collagen tissue that connects muscles to bones and doesn't secrete any fluid. 
The ligament is a band of flexible fibrous connective tissue that connects bone to bone and doesn't secret any fluid. 
Cartilage is a tough and flexible material that acts as a cushion between the bones of joints and doesn't secret any fluid. 
So the correct option is D.
