Explanation / Answer

Answer

1. False

Concentric lamellae- the tubular layers of bone surrounding the central canal in the osteon

2. TRUE

during isometric contraction, the length of muscle does not change

3. FALSE

The long bones in body present in lower limbs and upper limbs

4. FALSE

The meniscus is the C-shaped cartilages present in the knee joint and it absorbs shock and provides the movement of femur across the tibia.

5. TRUE

Ependymal cells line the inner cavities of the CNS that is in ventricles of the brain and secretes CSF.

6. FALSE

7. TRUE

The optic canals are channels/ways found in the lesser wings. These lesser canals are present in sphenoid bone

8. TRUE

The catecholamines are monoamines.

9.FALSE

synostosis if the immovable type of joint. it is present in sutures.

10. FALSE

It consists of the gastrocnemius and soleus.

11. TRUE

The deficiency of acetylcholine neurotransmitter leads to the development of paralysis and myasthenia gravis.
