  • Question 1
    4 / -1

    In an adult human, how many bones are present as ear ossicles?

    Solution

    Six ear ossicles are present, three in each ear. They are malleus, incus and stapes.

  • Question 2
    4 / -1

    The cervical vertebra called axis provides head with sideways rotation. This can be because

    Solution

    Axis (second cervical vertebra) has a peg like process called odontoid process that fits into odontoid canal of atlas (first cervical vertebra).

  • Question 3
    4 / -1

    Humerus with Its rounded upper end (head) articulates into:

    Solution

    Upper rounded end of the humerus (bone of arm) is called head that articulates into the glenoid cavity of the pectoral girdle (shoulder girdle).

  • Question 4
    4 / -1

    Smallest bone in human system is

    Solution

    Stapes, one of the ear ossicles, is the smallest bone in human body.

  • Question 5
    4 / -1

    Collar bone is known as

    Solution

    Clavicle (collar bone) is the bone of pectoral girdle, It articulates with the acromion process of the scapula.

  • Question 6
    4 / -1

    Acromion process is characteristically found in the __________ of mammals.

    Solution

    Each pectoral girdle consists of two bones -1 clavicle and 1 scapula. The scapula consists of a sharp ridge, the spine and a triangular body. The end of the spine projects as a flattened and expanded process called acromion. This process articulates with the clavicle

  • Question 7
    4 / -1

    Total number of bones in a hindlimb of a man is

    Solution

    Each hind limb consists of 30 bones 1 femur, 1 patella, 1 tibia, 1 fibula, 7 tarsals, 5 metatarsals and 14 phalanges.

  • Question 8
    4 / -1

    A cricket player is fast chasing a ball in the field. Which one of the following groups of bones are directly contributing in this movement?

    Solution

    Trasals, femur, metatarsals and tibia are bones of the legs which are involved in running during chasing the ball by a cricket player.

  • Question 9
    4 / -1

    The shoulder blade is made of

    Solution

    Scapula or shoulder blade is a bone of the pectoral girdle. It is a flat triangular bone, providing anchoroge for the muscle of the forelimb and an articulation for the humerus at the glenoid cavity.

  • Question 10
    4 / -1

    Cranium of human contains

    Solution

    Cranium consists of 8 bones-1 frontal, 2 parietal, 2 temporal, 1 occipital, 1 sphenoid and 1 ethmoid.

  • Question 11
    4 / -1

    Lumbar vertebra are found in

    Solution

    There are five lumbar found in the abdominal region in humans. They extend from the twelfth thoracic vertebra down to the sacral vertebrae.

  • Question 12
    4 / -1

    Ends of long bones are covered with

    Solution

    Hyaline cartilage is present at the end of long bones, Hyline cartilage consists of clear, large amount of translucent, slightly elastic matrix with less fibres.

  • Question 13
    4 / -1

    Which of the following bones form a link between axial and appendicular skeleton?

    Solution

    Clavicle is a bone that forms part of the pectoral girdle (part of appendicular skeleton) linking the scapula to the sternum (part of axial skeleton).

  • Question 14
    4 / -1

    Out of the following pairs of the human skeletal parts, identify the wrongly matched pair

    Solution

    Clavicle and glenoid cavity are skeletal parts pelvic girdle.

  • Question 15
    4 / -1

    The coxal of the pelvic girdle is formed by the fusion of

    Solution

    The pelvic girdle is composed of two coxal (hip) bones. Each coxal bone consists of three separate parts: the ilium (short and straight bone), the ischium (lower elongated bone running parallel to vertebral column) and the pubis (inner smaller bone).

  • Question 16
    4 / -1

    Which of the following statements are incorrect regarding a normal human?
    (i) The skull is dicondylic.
    (ii) Metacarpals are five in numbers.
    (iii) Patella is a cup-shaped bone covering the knee dorsally.
    (iv) Scapula is a large triangular flat bale, situated on the ventral side of the thorax.
    (v) The pelvic girdle has two coxal bones.

    Solution

    Patella is a cup-shaped bone covering and protecting the anterior surface of the knee joint. Scapula is a large triangular flat bone, situated on the dorsal side of the thorax.

  • Question 17
    4 / -1

    Human vertebral column consists of 33 vertebrae and ________ bones

    Solution

    Theoretically, human vertebral column consists of 33 vertebrae - 77 cervical, 12 thoracic, 55 lumbar, 55 sacral and 44 coccygeal. However, it consists of 26 bones as five sacral vertebrae fuse to form one sacrum and four coccygeal vertebrae fuse to form one coccyx.

  • Question 18
    4 / -1

    Appendicular skeleton includes

    Solution

    The endoskeleton of mammals have two major divisions: (i) Axial skeleton, that lies along the longitudinal axis of the body. It supports and protects the organs of the head, neck and trunk. It includes skull, ribs, sternum and vertebral column, (ii) Appendicular skeleton, which is associated with the appendages. It consists of two girdles, the pectoral and pelvic girdles and the limb bones.

  • Question 19
    4 / -1

    11th and 12th pair of ribs which are imperfectly formed and do not reach the sternum are called

    Solution

    The last two pairs of ribs (11th and 12th) are called floating ribs as their anterior ends are not attached to either the sternum or the cartilage of another rib. The floating ribs provide protection to kidneys.

  • Question 20
    4 / -1

    Skull of man is

    Solution

    Skull of man is called dicondylic because it has two small protuberances known as occipital condyles at the posterior end. These condyles articulate with the atlas vertebra.

  • Question 21
    4 / -1

    Which of the following is not a function of vertebral column?

    Solution

    Tarsals and metacarpals are the bones of the limb, therefore, they are the part of appendicular skeleton and not the axial skeleton which consists of vertebral column.

  • Question 22
    4 / -1

    The figure given here is of rib cage. Identify the parts labelled as A, B and C and select the correct option.

    Solution

    A - Sternum
    B - Ribs
    C - Vertebral column

  • Question 23
    4 / -1

    Consider the following four statements (i) - (iv) and select the correct option.
    (i) Actin is present in thin filament.
    (ii) H-zone of striated muscle fibre represents both thick and thin filaments.
    (iii) There are 11 pairs of ribs in man.
    (iv) Sternum Is present on ventral side of the body.

    Solution

    Actin is a globular protein present in thin filaments. There are 12 pairs of ribs in man. Sternun is a flat bone present on the ventral side of the body in the middle of the front of the chest.

  • Question 24
    4 / -1

    The lower jaw in mammals is made up of

    Solution

    Dentary is either of a pair of membrane bones of the lower jaw of most vertebrates. In lower forms it is restricted the distal area but in recent higher mammals, it forms e body of the mandible.

  • Question 25
    4 / -1

    Match column I with column II and select the correct option from the codes given below. 

    Solution

    The first 7 pairs of ribs are called true ribs as their anterior ends are attached directly to the sternum. The 8th, 9th and 10th pairs are called false ribs as they are attached indirectly to the sternum. The 11th and 12th pairs are called floating ribs as their anterior ends are not attached to sternum.
