STRUCTURES OF CNS
Enzyme Related to CNS:
- Phospholipase A2 (PLA2) is involved in the breakdown of phospholipids in the brain.
- Acetylcholinesterase is involved in the breakdown of acetylcholine in the synapses of the nervous system.
- Monoamine oxidase (MAO) is involved in the breakdown of monoamine neurotransmitters in the brain.
Homoeopathic Drugs Related to CNS:
- Opium is related to the opioid receptors in the brain and spinal cord.
- Aconitum is related to the hypothalamus and pituitary gland.
- Ignatia is related to the emotional centers of the brain.
- Phosphorus is related to the phospholipids in the brain.
- Lachesis is related to the pituitary gland and thyroid gland.

CNS Development:
- Step 1 → Step 2 → Step 3
- Step 1: Formation of the neural plate ( ectoderm)
- Step 2: Folding of the neural plate to form the neural groove
- Step 3: Closure of the neural groove to form the neural tube
Pathway of Sensory Nerve Fibers:
- Step 1 → Step 2 → Step 3
- Step 1: Receptor cells in the sensory organs (peripheral receptors)
- Step 2: Afferent nerve fibers carry signals from the receptor cells to the spinal cord
- Step 3: Processing of sensory information in the brain
Blood Supply of CNS:
- Arteries → Veins
- Arteries: Internal carotid artery, vertebral artery
- Veins: Internal cerebral veins, basal veins
Muscle Action Sequence:
- Step 1 → Step 2 → Step 3
- Step 1: Excitation of motor neurons in the spinal cord
- Step 2: Conduction of the impulse to the muscles via motor nerve fibers
- Step 3: Contraction of the muscles
