Which of the following is the property of cardiac muscle?

  1. It is involuntary muscles.

  2. It is resistant to fatigue.

  3. It is striated muscle.

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

  • Cardiac muscle is specialized tissue that is found only in the heart.
  •  It has characteristics similar to both smooth and skeletal muscle tissue, as well as specialized properties, that allow it to function with fast but sustained contractions, rapid conduction and coordinated movement. Hence,  the property of cardiac muscle is involuntary muscles, resistant to fatigue and striated muscle.
So, the correct answer is 'all the above'.

Cardiac muscles are resistant to fatigue.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Normal muscles like the skeletal muscles get fatigued (strenuous activities like exercise, sports etc.) due to the formation of lactic acid as a result of anaerobic glycolysis. But cardiac muscles do not form lactic acid due to the presence of rich capillary network which provides enough oxygen to the muscles. Anaerobic processes never occur in cardiac muscles, hence lactic acid is never formed enabling heart muscles to perform their function without fatigue.
Therefore, the statement that cardiac muscles are fatigue resistant is true.

Gastrocnemius muscles are found in

  1. Fore arm

  2. Chest

  3. Thigh

  4. Shank
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The two major types of muscles that make up the calf (back portion of the lower leg) are gastrocnemius and soleus muscle.
  • Along with the soleus muscle, the gastrocnemius forms half of the calf muscle. Its function is plantar flexing the foot at the ankle joint and flexing the leg at the knee joint.
  • Hence gastrocnemius muscles are found in shank(a person's leg, especially the part from the knee to the ankle).
  • So, the correct answer is 'Shank'.

Read the following matches 
(i)   Glenoid cavity            - Scapula
(ii)  Bicipital tuberosity     - Humerus
(iii) Styloid process           - Ulna
Which of these is correct?

  1. (i) and (ii)

  2. (i) & (iii)

  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.
