QUESTION 5 Which of the following is true regarding cranial nerves? a The optic nerve and occulomotor nerve have the same function D. cranial nerves with sensory components are responsible for carrying input from the 5 senses to the brain the olfactory nerve, occulomotor nerve and abducens nerve are responsible for eye movement d- all cranial nerves except CNVIII are present in pairs C c. QUESTION 6 An action potential: a requires the cell membrane to be polarized at rest D includes depolarization, or movement of positively charged sodium ions into the cell C. is the flow of electricity along an axon to the synaptic knob d. all of the above ??.

Explanation / Answer

5. B) cranial nerves having sensory components are responsible for carrying inputs from 5 senses to the brain.Examples of sensory nerve include olfactory nerve, optic nerve, Vestibulocochlear nerve

6.d. all of the above Action potentials are generated by special types of voltage-gated ion channels which inward flow of sodium ions, which changes the electrochemical gradient, causing membrane depolarization (positive charge) and  propagates as a wave along the axon towards the synaptic knobs (axon terminals)
