Splanchnic nerve
Vagus nerve
The gallbladder is primarily innervated by the vagus nerve (cranial nerve X), which provides parasympathetic stimulation. Additionally, sympathetic innervation comes from the celiac plexus, particularly through the greater splanchnic nerve. This dual innervation helps regulate gallbladder contraction and bile release.
The gallbladder is responsible for storing extra bile produced by the liver. When bile is needed for digestion, the gallbladder contracts and releases it into the small intestine.
The phrenic nerve.
ulnar nerve
The nerves responsible for causing headaches are the trigeminal nerve and the occipital nerve.
median nerve
NEUROTRANSMITTER is responsible for transmission of nerve impulses.Eg.dopamine,acetylcholine etc.
The trigeminal nerve is primarily responsible for sensory functions.
The olfactory nerve which is also cranial nerve number 1 is responsible for the sense of olfaction.
Trigeminal V: a mixed nerve responsible for the chewing of food and sensations in the face, scalp, and teeth and the contraction of chewing muscles.
Cranial Nerve 2 - Optic Nerve
