Zoology MCQs for NEET — Practice Questions with Answers

Each human leg contains 30 bones. This includes the femur, tibia, fibula, patella, and the bones of the foot (tarsals, metatarsals, and phalanges).

The phalanges of the human hand and foot follow a specific formula. In the hand, the digits are arranged in a 2,3,3,3,3 pattern, meaning the thumb has 2 phalanges and the other fingers each have 3. In the foot, the big toe has 2 phalanges and the other toes have 3 each. Therefore, the correct formula for phalanges of hand and leg is 2,3,3,3,3.

In each human limb, there are 7 tarsal bones and 5 metatarsal bones. The tarsals form the ankle and the back part of the foot, while the metatarsals form the middle part of the foot. Therefore, the correct numbers are 7 tarsal bones and 5 metatarsal bones.

The human axial skeleton consists of 80 bones. These include the bones of the skull, the vertebral column, and the thoracic cage. Specifically, it includes 22 bones in the skull, 26 in the vertebral column, 1 hyoid bone, and 25 bones in the thoracic cage (including the sternum and ribs).

In each forelimb of a human, there are 8 carpal bones and 5 metacarpal bones. The carpals are the bones that form the wrist, and the metacarpals are the bones that form the palm of the hand.

The pectoral girdle (shoulder girdle) is made up of two bones: the clavicle (collarbone) and the scapula (shoulder blade). Therefore, both clavicle and scapula together form the pectoral girdle.

The pelvic girdle is composed of three bones: the ilium, ischium, and pubis. These three bones are fused together in adults to form the hip bone.

The shank, or lower part of the leg, contains the tibia and fibula bones. In frogs, these bones are fused and referred to as the tibio-fibula.

Humans have 7 cervical vertebrae. These vertebrae are located in the neck and are designated C1 through C7.

Amoeboid movement is facilitated by structures called pseudopodia, which are temporary projections of the cell membrane and cytoplasm.
