Solution

The correct option is D Associated with myelinated and non-myelinated nerve fibre
There are two types of Schwann cells, myelinating and non-myelinated. Myelinating Schwann cells wrap around axons of motor and sensory neurons to form the myelin sheath. Schwann cells are involved in many important aspects of peripheral nerve, conduction of nervous impulses along axons, nerve development and regeneration, trophic support for neurons, production of the nerve extracellular matrix, modulation of neuromuscular synaptic activity and presentation of antigens to T-lymphocytes.

Q. Read the given statements and select the correct option.
(i) Synaptic cleft of neurons secretes adrenaline.
(ii) Myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon.
(iii) Non-myelinated nerve fibre is enclosed by a Schwann cells that does not form a myelin sheath.
(iii) Spinal and cranial nerves are made of non-myelinated nerve fibres

Q. Consider the following statements and state true or false.
1. Synaptic cleft of neurons secrete adrenaline.
2. Myelinated nerve fibres and enveloped with Schwann cells, which form a myelin sheath around the axon.
3. Non-myelinated nerve fibre is enclosed by a Schwann cell that does not form a myelin sheath.
4. Spinal cord and cranial nerves are made up of non-myelinated nerve fibres.

Q. Consider the following statements and find out coorect option:
(a) Three are two types of axons, namely myelinated and non myelinated
(b) Myelinated nerve fibres found in autonomous and the somatic neural systems
(c) The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon.
(d) The gap between two adjacent myelin sheaths are calleds nodes of Ranvier.
(e) Unmyelinated nerve fibre found in spinal and cranial nerves
(f) Unmyelinated nerve fibre is enclosed by a Schwann cell that does not form a myelin sheath around the axon.

A myelinated nerve fibre is enveloped by Schwann cells, which form a myelin sheath around the axon.

An unmyelinated nerve fibre is not enclosed by a Schwann cell and hence does not form a myelin sheath around the axon.

Q. Assertion :Myelin sheath insulates nerve fibre and prevents its depolarization Reason: Nerve impulses are conducted more rapidly in non-myelinated fibres than myelinated ones
