Question

Please put these terms in order of how a nervous system signal would travel in order to communicate with a muscle within the blood vessels of the skin.

Terms:

white ramus communicans, ventral root, ventral ramus, dorsal root, spinal nerve, gray ramus communicans, and sympathetic trunk

Answer 1

Most arteries and veins in the body are innervated by sympathetic adrenergic nerves, which release norepinephrine (NE) as a neurotransmitter. Some blood vessels are innervated by parasympathetic cholinergic or sympathetic cholinergic nerves, both of which release acetylcholine (ACh) as their primary neurotransmitter.

Taking sympathetic system into consideration the pathway of nerve supply are -

These grey rami communicans exist at every level of the spinal cord and are responsible for carrying postganglionic nerve fibres from the paravertebral ganglia to their destination . Similarly celiac plexus supplies the blood vessels of gut.
