  • Question 1
    1 / -0
    The backbone is not a single bone. It is made up of ____bones.
    Solution
    The normal average person is born with a total of 33 vertebrae in the vertebral column (backbone). By the time the person becomes an adult, some bones fuse and the number is reduced to 24. The articulating vertebrae are named according to their region of the spine. There are seven cervical vertebrae, twelve thoracic vertebrae, and five lumbar vertebrae.
    Hence the correct answer is option A.
  • Question 2
    1 / -0
    Bone which is formed by ossification in the tendon of muscle is _______.
  • Question 3
    1 / -0
    The longest bone in our body is the ____.
    Solution

    Solution:

    Correct answer is option A.

    Explanation for correct option:

    • As we know human body is made of skeleton. Skeleton is structure that keeps body in shape and helps in movement.
    • In adult humans there are 206 bones in skeleton. Bones along with muscles and joints assists in various function in our body.
    • The femur (thigh bone) is the longest bone in the human body and the shortest bone is the stapes found in the middle ear.

  • Question 4
    1 / -0
    External ear (pinna) is a firm, flexible structure composed of: 
  • Question 5
    1 / -0
    The hip region consists of
    Solution
    Figure showing: Joints of human body; see the hip region
    The hip region also called as pelvis consists of the pelvic bones or the hip bones which is formed by ball and socket type of joints. The pelvic bones are the strongest bones in the human body, and  show a maximum rotation of 360 degrees. Hence, the hip region consists of pelvic bones.
    So, the correct answer is 'Pelvic bones'

  • Question 6
    1 / -0
    Hinge joints are present in the ........... region.
    Solution
    Our body is made up of many joints. Each of these joints is of different categories and perform specific functions. They may be movable joints or immovable joints. Among the movable joints, some are hinge joints. This means that they are able to move about one axis. They are a type of synovial joint.
    So the correct option is C.
  • Question 7
    1 / -0
    A snail moves with the help of its ____.
    Solution
    • There are different modes of locomotion in different animals. 
    • Snails have small muscular foot at the bottom of their bodies. 
    • They move with the help of these small muscular feet. 
    • Their body releases mucus which helps in movement and also prevents drying up of their bodies.

    So, option D "Feet" is the correct answer.

  • Question 8
    1 / -0
    Which of the following statements is not true?
    Solution
    All animals exhibit different patterns of movements. 
    Example: In birds, the forelimbs are modified to result in wings, which leads to flying movement. 
    In case of kangaroos, the hind limbs are modified such that they contain flexible muscles resulting in their jumping movement. 
    In humans, the legs are modified so that they walk with two limbs only, as opposed by other vertebral mammals like dogs, cats etc. which have 4 limbs.
    Cockroaches are capable of flying, walking and climbing. 

    Hence the statement, 'all animals show exactly same movements' is false.
    So, the correct answer is option B. 
  • Question 9
    1 / -0
    Rotation of arm in a full circle is possible due to ............ joint
    Solution
    • The arm is joined to the shoulder girdle/ pectoral girdle by the ball and socket type of joint. The ball and socket joint is the strongest type of joint in the human body. It provides a maximum rotation of 360 degrees i.e full circle/ circumvention. This makes possible the rotation of the arm in a full circle.
    • Gliding joint is also known as a plane joint or planar joint. It is a common type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. These joints are found in the articulations between the bones of the wrist and those of the ankle.
    • Pivot joint is a type of synovial joint, also called rotary joint, or trochoid joint. It is freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. Example: pivot joint between radius and ulna of the forearm.
    • The hinge joint is a common class of synovial joint that includes the ankle, elbow and knee joints. Maximum rotation is 180 degrees.
    Thus, rotation of the arm in a full circle is possible due to ball and socket type of joints.
  • Question 10
    1 / -0
    Another name for the shoulder joint is
    Solution
    The shoulder joint/ glenohumeral joint is a type of ball and socket joint. The ball and socket joint also called as a spheroidal joint. It is a joint in which the ball-like rounded surface of a bone moves within a cup-like depression on another bone, this allows greater freedom of movement than any other kind of joint. Maximum rotation in ball and socket joints is 360$$^o$$ i.e. full circle.
    Hence, as the shoulder joint is of ball and socket type, hence it is also named as 'ball and socket joint'.
