Multiple choice biology skeleton, joints and muscles skeleton our skeletal system and the skin skeleton - movement and locomotion

We move our hands while walking for

  1. Faster movement

  2. Balancing

  3. Increasing blood circulation

  4. Relieving tension
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • We move our hands while walking is a natural motion wherein each arm swings with the motion opposite that of the leg.
  • Moving arms in an opposing direction with respect to the lower limb reduces the angular momentum of the body which helps in balancing the rotational motion produced during walking.
  • Hence we move our hands while walking for balancing.
  • So, the correct answer is 'Balancing'.

Biceps is attached with

  1. Radius

  2. Ulna

  3. Femur

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The biceps is a muscle on the front part of the upper arm. The biceps includes a “short head” and a “long head” that work as a single muscle.
The biceps is attached to the arm bones by tough connective tissues called tendons. The tendons that connect the biceps muscle to the shoulder joint in two places are called the proximal biceps tendons. The tendon that attaches the biceps muscle to the forearm bones (radius and ulna) is called the distal biceps tendon. When the biceps contracts, it pulls the forearm up and rotates it outward.
So the correct answer is 'Radius and Ulna'.

Epiphyseal discs, which are present at the ends of long
bones are responsible for

  1. Bone elongation

  2. Growth of thickness of the bone

  3. Kemoaemng me shape at bone

  4. Formation of Haversian canal

A Correct answer
Explanation

Epiphyseal plate (hyaline cartilage) is formed between diaphysis and epiphysis. This contributes in bone elongation.

Olecranon process occurs in

  1. Femur

  2. Radius

  3. Humerus

  4. Ulna
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The bones of the hand (forelimb) are humerus, radius and ulna, carpals (wrist bones – 8 in number), metacarpals (palm bones – 5 in number) and phalanges (digits – 14 in number).
  • The olecranon is the near end of the ulna which forms the pointed portion of the elbow.
  • Hence ulceranon process occurs in ulna.
  • So, the correct answer is 'Ulna'.

Glenoid cavity is associated with

  1. Scapula

  2. Humerus

  3. Femur

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • A pectoral girdle or shoulder girdle attach the bones of upper limb to the axial skeleton.
  • Each pectoral girdle is formed of two halves. Each half of pectoral girdle consists of a scapula and clavicle. 
  • Glenoid cavity is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It articulates with the humerus to form the shoulder joint. Hence glenoid cavity is associated with scapula and humerus.
  • So,the correct answer is 'Both A and B'.

The digital formula for the hind limbs of frog is

  1. $0,2,2,3,3$
  2. $2,2,3,3,3$
  3. $2,2,3,4,3$
  4. $0,2,1,2,3$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Digital formula is a way of comparing animals by the number of phalanges that they have in each of their digits. It can be used to study phylogeny or to predict how an animal may use its hands and feet. An animal’s phalangeal formula is simply given as a series of numbers. Most land mammals including humans have a 2-3-3-3-3 formula in both the hands(or paws) and feet. Fore limb of frog is 0-2-2-3-3 and hind limb is 2-2-3-4-3.

So, the correct answer is ‘2-2-3-4-3’.

Humerus bone is present in the

  1. Upper arm

  2. Lower arm

  3. Lower jaw

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

The humerus is the single bone of the upper arm region. It articulates with the radius and ulna bones of the forearm to form the elbow joint. Distally, the humerus becomes flattened. The much smaller lateral epicondyle of the humerus is found on the lateral side of the distal humerus.

So, the correct option is 'Upper arm'.

One of the following is a sesamoid bone in man?

  1. Periotic

  2. Ramus

  3. Clavicle

  4. Patella
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A bone embedded in the tendon is known as a sesamoid. They are usually found in the joints of the body. The patella in the knee of a man is the largest sesamoid bone present in the human body.
So, the correct answer is 'Patella'.

A curved bone is structurally designed to

  1. Accommodate easily in body

  2. Absorb the stress of the body weight at several different points so that the stress is evenly distributed

  3. Provide more area for attachment of muscles

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

 Long bones are longer than they are wide and they are slightly curved for strength.
– A bone that is curved is structurally able to absorb the stress of the body at several points so the stress will be evenly distributed.
– The straight bone would not be able to evenly distribute the weight of the body and the bone would break more easily.
– Long bones are shaped like tubes with rounded ends that are designed to fit into other bones to form joints.
– The ends of long bones are filled with spongy bone; this makes them light but strong.
– Long bones can be found in the thigh, lower leg, toes, arms, forearms and fingers.
