1. Meninges- it consist of durameter arachnoid and piameter. Piameter is innermost. 2. choroid plexusproduce cerebrospinal fluid. It acts as a cushion for the brain\'s cortex and spinal chord and also act as blood brain barrier. 3. corpus callosum, which helps in communication between the right and left brain hemispheres, is present only in placental mammals. 4.The brainstem connects to the spinal cord and consists of the medulla oblongata, pons and midbrain. 5. external ear is called Auricle or pinna 6. Three bones in the middle ear (tympanic cavity): the hammer (malleus), the anvil (incus) and the stirrup (stapes). The vibrations are transmitted further into the ear via them. 7. An organ in our inner ear, the labyrinth, is important for our equilibrium. 8. Vitreous humour is the transparent jelly-like tissue filling the eyeball between the lens and retina. It protects retina. 9. three layes of eye : fibrous tunic (the outer layer of the eyeball), vascular tunic and nervous tunic. 10. Extraocular muscles Solution 1.
