Sagot :
Answer:
1. vi. Preganglionic
2. vii. adrenergic
3. ii. sympathetic chain ganglia
4. iii. Craniosacral
5. viii. splanchnic
Explanation:
Action potential travel down preganglionic nerve fibre. They travel towards Vagus Nerve near the effector organ. These impulses arrive at cardiac plexus, which create action potential in postganlianic.
A cell that connects the body to receive the signal from the brain to do the action is called a neuron and the tissue system is called the nervous system.
The answer to the following question is as follows:-
- Action potentials travel along with the nerve fiber and enter the Preganglionic
- Fibers exiting take one of three routes: the spinal nerve route, the sympathetic nerve route, and the adrenergic nerve route.
- Arriving at target cells sympathetic chain ganglia nerve fibers release acetylcholine or norepinephrine into the synaptic cleft.
- Also known as the Craniosacral division, the sympathetic nervous system exits the preganglionic CNS via the spinal nerves from T1-L2.
- The effect of norepinephrine binding to splanchnic receptors stimulates cardiac muscle cells.
Hence, these are the answer to the question.
