  1. cartilaginous joint

  2. hinge joint

  3. fibrous joint

  4. synovial joint

Show answer
Correct Option: C
Explanation:

The type of joint between the human skull bones is called 'fibrous joint'. So, the correct answer is (c).

Synovial joint is exemplified by:

  1. Pivot joint

  2. Hinge joint

  3. Ball and Socket joint

  4. All of these

Correct Option: D

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

zoology musculo - skeleton system gait of animals basics of joints joints and type of joints skeleton, joints and muscles

  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.

Show answer
Correct Option: A
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

Show answer
Correct Option: D
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

Show answer
Correct Option: D
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

Show answer
Correct Option: D
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.

Major constituent of human body is

  1. Skeleton

  2. Muscles

  3. Connective tissue

  4. Extracellular fluid

Show answer
Correct Option: A
Explanation:

  • A skeleton is the hard structure that protects the internal organs of a living thing. 
  • Skeletons can be inside the body or outside the body. 
  • In mammals, which include humans, the skeleton is made of bones. 
  • All the bones, when they are joined together, make the "skeletal system" of a body. Hence, the major constituent of the human body is a skeleton.
So, the correct answer is 'skeleton'.

Which is not the function of bones?

  1. Protection of vital organs

  2. Haemopoiesis

  3. Muscle attachment

  4. Secretion of hormones

Show answer
Correct Option: D
Explanation:

The endocrine glands in the body such as a pituitary gland, thymus, thyroid gland, parathyroid and etc secrete various hormones in the body. The bones cannot secrete hormones as they lack glands to produce and secrete hormones. It helps in protection of vital organs, haemopoiesis, and muscle attachment.

So, the correct answer is 'Secretion of hormones'.

  1. Support

  2. Hearing

  3. Sound production

  4. All of the above

Show answer
Correct Option: A
Explanation:

The skeleton is the structural framework of the body. Our skeleton system contains 206 bones. Its main function is to support muscles and tissues. It also protects the vital organs, allows movement of bones and muscles and serves as the storage house for immature blood cells and minerals.

So, the correct option is A.
