  3. (i) and (iii)

  4. All are correct
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A- The glenoid cavity or glenoid fossa of scapula is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula.

B- The rough eminence which is on the anterior inner aspect of the neck of the radius and into which the tendon of the biceps is inserted.
C- The styloid process of the ulna is found at distal end of the forearm, and projects from the medial and back part of the bone.

So, the correct option is 'Option B'.

Which bones are present in both hands and foot? Name the only movable bone in the skull of man.

  1. Tibia - Maxilla

  2. Radius - Lacrimal

  3. Phalanges - Mandible

  4. Phalanges - Maxilla
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The phalanges are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges.
  •  Hence, Phalanges are present in both hands and foot.
  • The mandible is the largest, strongest and lowest bone in the human face. It forms the lower jaw and holds the lower teeth in place. The mandible is the only movable bone of the skull, not counting the ossicles of the middle ear.
  • Hence, Mandible is the only movable bone in the skull of the man.
  • So, the correct answer is 'Phalanges - Mandible'.

Which of the following is not fully formed in birds?

  1. Pectoral girdle

  2. Pelvic girdle

  3. Hind limb

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

The main characteristic that is associated with birds is their ability to fly. The entire forelimb has been modified to become a wing. The forelimb is not required to support weight but to restrain prey or for locomotion.

In the middle lateral side a cup shaped cavity or acetabulum (for head of femur) is present in the region of union of

  1. Ilium and ischium

  2. Ilium and pubis

  3. Ilium, ischium and pubis

  4. Ischium and pubis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The hip joint is a synovial joint formed by the articulation of the rounded head of the femur and the cup-like acetabulum of the pelvis. The cup-like acetabulum forms at the union of three pelvic bones - the ilium, pubis, and ischium. 

So, the correct option is C. (ilium, ischium and pubis)

Bones act as ________ during locomotion.

  1. Levers

  2. Fulcrum

  3. Pulleys

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

Bones provide a supporting structure for the body. It gives a framework to the body that helps in maintaining the shape to the body and they also provide surface so that muscles can be attached. Further. bones act as a lever during locomotion so it is able to turn one axis.
Hence , option  A ( Levers ) is correct.

A cup shaped cavity for articulation of femur head is

  1. Acetabulum

  2. Glenoid cavity

  3. Sigmoid notch

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

Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones ilium, ischium and pubis. At the point of fusion of the above bones is a cup shaped cavity called as acetabulum to which the thigh bone articulates. The two halves of the pelvic girdle meet ventrally to form the pubic symphysis containing fibrous cartilage.

Which one is the bone of fore limb?

  1. Humerus

  2. Femur

  3. Tibia

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

The bones of the limbs along with their girdles constitute the appendicular skeleton. Each limb is made of 30 bones. The bones of the hand (fore limb) are humerus, radius and ulna, carpals (or wrist bones 8 in number), metacarpals (palm bones, 5 in number) and phalanges (digits 14 in number).

Longest bone of human skeleton is

  1. Femur

  2. Humerus

  3. Tibia

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

In humans, each limb is made of 30 bones. The bones of the legs (hind limb) are femur (thigh bone, the longest bone), tibia and fibula, tarsals (ankle bones 7 in number), metatarsals (5 in number) and phalanges (digits 14 in number). A cup-shaped bone, called as patella covers the knee ventrally (knee cap).
