Skeletal and Muscular System Questions

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

Sutural joints are present between

  1. Thumb and metatarsal

  2. Humerus and radius-ulna

  3. Parietals of skull

  4. Glenoid cavity and pectoral girdle
Reveal answer Fill a bubble to check yourself
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'.

Identify the correct description.

  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.
Reveal answer Fill a bubble to check yourself
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.
Reveal answer Fill a bubble to check yourself
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.

Innominate is

  1. A nerve and an artery

  2. A nerve and a vein

  3. A vein and an artery

  4. A part of skeleton and an artery
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Term innominate is used both in the context of a skeletal system and circulatory system. In the circulatory system, innominate is one of the branches of the aortic arch. The arch of the aorta, located immediately beyond the ascending aorta, gives off three large branches.
1. The brachiocephalic trunk is a short artery formerly called the innominate. Its name means that is supplies the head and the arm. After extending upward somewhat less than 5 cm (2 inches), it divides into the right subclavian artery, which supplies the right side of the head and the neck. 
2. The left common carotid artery extends upward from the highest part of the aortic arch. It supplies the left side of the neck and the head.
3. The left subclavian artery extends under the left collar bone (clavicle) and supplies the left upper extremity. This is the last branch of the aortic arch.
Innominate bone in anatomy refers to either of the two bones that form the sides of the pelvis, consisting of three fused components, the ilium, ischium, and pubis. The non-technical name is hip bone.

Skeleton is the site of

  1. Regulation

  2. Haemoglobin

  3. Haematopoiesis

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

  • The skeleton is the site of haematopoiesis, the development of blood cells that takes place in the bone marrow. 
  • In children, haematopoiesis occurs primarily in the marrow of the long bones such as the femur and tibia. 
  • In adults, it occurs mainly in the pelvis, cranium, vertebrae, and sternum. Hence, the Skeleton is the site of Haematopoiesis.
So, the correct answer is 'Haematopoiesis'.

Sesamoid bones are commonly found in ______________.  

  1. Vertebral column

  2. Ribs

  3. Skull

  4. Palm of hands
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sesamoid bones develop in some tendons in locations where there is considerable friction, tension and physical stress. They are typically found in palm of hands and soles of feet. Therefore, (d) is the correct answer.

C Correct answer
Explanation

  1. Innominate is used to designate many parts otherwise unnamed.
  2. Innominate artery is a great part of the arch of the aorta.
