D Correct answer
Explanation

A hinge joint is a common class of synovial joint that includes the ankle, elbow and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to fold or extend. The elbow is a more complex hinge joint that forms between the humerus of the upper arm and the ulna and radius of the forearm. So, the correct answer is 'Hinge'.

A 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 ulna is a long and curved bone.
  • Proximally, the ulna articulates with the humerus at the elbow joint. Distally, the ulna articulates with the radius, forming the distal radio-ulnar joint.
  • So, the correct answer is 'Long and curved bone'.

D Correct answer
Explanation

The skeleton serves a number of functions in vertebrates:

(1) The skeleton forms a rigid framework, which gives support to the body against gravity.
(2) The skeleton encloses the more vital organs of the body to protect them from injury.
(3) Bones contain deposits of calcium phosphate and calcium carbonate. These may be released into the blood if needed for use elsewhere in the body, but are later replaced. This helps in regulating calcium and phosphorus level of blood. 
So, the correct answer is option D.

B Correct answer
Explanation

  • The skull is composed of two parts: the cranium and the mandible.
  •  In the human, cranium has two parts the neurocranium and the viscerocranium. 
  • The neurocranium forms the cranial cavity that surrounds and protects the brain and brainstem. 
  • The neurocranium consists of the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid, and frontal bones—all are joined together with sutures. Hence, The brain is protected by the Cranium.
So, the correct answer is 'Cranium'.
