GENERAL HISTOLOGY

Detailed explanation-1: -Parasympathetic ganglia Those ganglia can be found both in head and neck (and they are part of the cranial nerves) and in the trunk, close to the thoracic and abdominal/pelvic organs. Their preganglionic neurons are located in the cranial nuclei of the brainstem, and in the lateral horn of the sacral spinal cord.

Detailed explanation-2: -The targets of these fibers are terminal ganglia, which are located near-or even within-the target effector. These ganglia are often referred to as intramural ganglia when they are found within the walls of the target organ.

Detailed explanation-3: -The myenteric plexus lies in between the outer longitudinal and inner circular smooth muscle layers of the intestines. By stimulating these muscles, it controls motility along the gastrointestinal tract.

Detailed explanation-4: -The myenteric plexus, also known as the Auerbach plexus, is a network of autonomic motor nerve fibers located in the muscular layers of digestive organs.
