Explanation / Answer
Question 1
Answer is D
that is lacrimal bone is not the skull bone. it is facial bone.
skull bones are
i. Frontal bone
ii. Two parietal bones
iii. Two temporal bones
iv. Occipital bone
v. Ethmoid bone
vi. Sphenoid bone
Question 2
Answer is A
Tendon means the connection between bone and muscle
The connection between two bones is called ligament
joining of two surfaces by sewing is called suture.
Question 3
Answer is D
that is biceps femoris which is found in thigh at femur bone
The muscle found in arm are
brachioradialis
Coracobrachialis
flexor carpi radialis
deltoid
Question 4
Answer is B that is oligodendrocytes
These are coats on axons specilised membrane present on axons called myelin sheath which provide insulation to the axons to propagate signals more efficiently.
Schwann cells; these are found in peripheral nervous system and function is similar to Oligodendrocytes.
microglia are specilised macrphages found in CNS and provide phagocytosis.
