Correct Answer � C

Explanation

• CNS (brain, spinal cord),

• Astrocytes

• Sensory neurons of 5^th, 7^th, 8^th, 9^th. 10^th cranial nerve ganglia (trigeminal, geniculate, sphenopalatine, submandibular, cochlear, vestibular, otic and vagal parasympathetic ganglia).

• Oligodendrocytes

• Sensory neurons of spinal dorsal root ganglia.

• Ependymal cells

• Sympathetic chain ganglia and plexus (celiac/preaortic/renal ganglia, enteric plexus in GIT, I.e. Auerbachs and Meissner’s).

• Retina

• Parasympathetic ganglia and plexus of GIT.

• Pineal gland

• Schwann cells of peripheral nerves, satellite cells of all ganglia.

• Neurohypophysis (posterior pituitary)

• Adrenal  medulla, chromaffin cells, parafollicular C-cells of thyroid gland.

• All cranial and spinal motor nerves

• Melanocytes and melanoblasts.

• Glomus cells

• Dermal bones of skull: Frontal, parietal, temporal, nasal, vomer, palatine, mandible, maxilla.

• Leptomeninges : arachnoid and pia mater (Duramater is mesodermal).

• Dentine of teeth (odontoblasts)

• Eye : choroid, sclera, iris epithelium, pupillary muscles (sphincter and dilator pupillae, ciliary muscles).

• Pharyngeal arch cartilages.

• Retinal pigmented epithelium

• Connective tissues of head including dermis, tendon, ligaments.

• Bulbar and coronal ridges of heart.
