Nervous System

Splanchnic nerve

motor nuerons
Nerve tissue carries electrical signals that affect muscle tissue. Nerve tissue's function is to move and coordinate the way the body functions.

The hypothalamus is part of the human brain. It has a wide variety of functions including linking the nervous system to the endocrine system.

Heavily myelinated, large diameter fibers

yes it is. it is one of the 5 senses

afferent/sensory neurons

Control of seizures during epilepsy.

changing the neuron membrane structure, which changes the shape of receptor proteins

I believe the muscle that you are refering to may be this one, it is known as an infraspinious muscle

= Infraspinatus muscle = Wikipedia, the free encyclopedia - Cite This Source

The Infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa. It attaches medially to the infraspinous fossa of the scapula and laterally to the greater tubercle of the humerus. It arises by fleshy fibers from its medial two-thirds, and by tendinous fibers from the ridges on its surface; it also arises from the infraspinatous fascia which covers it, and separates it from the Teres major and minor. The fibers converge to a tendon, which glides over the lateral border of the spine of the scapula, and, passing across the posterior part of the capsule of the shoulder-joint, is inserted into the middle impression on the greater tubercle of the humerus. The tendon of this muscle is sometimes separated from the capsule of the shoulder-joint by a bursa, which may communicate with the joint cavity. It is a lateral rotator of the glenohumeral joint and adductor of the arm. The Infraspinatus and Teres minor rotate the head of the humerus outward (external rotation); they also assist in carrying the arm backward. == ==

Other way, dude. Nerve fibers are just like electric wires. Just think of a Myelinated fiber as a wire with rubber on the outside, and unmyelinated with ought it. Electricity runs more efficiently through a wire that has rubber on it, and so do myelenated fibers, but with an added bonus, they are faster than their unmyelenated counterparts hope it helped!

Most parasympathetic motor pathways begin in the dorsal aspect of the medulla, in the dorsal motor nucleus of the vagus nerve. Parasympathetic motor pathways also come from the preganglionic cell bodies located in the lateral horn of the spinal cord in the sacral region (pelvic splanchnic nerves). Thus, the description cranio-sacral is often used to describe the origins of the parasympathetic innervation.

The brain processes sensory stimuli.

Information entering the central nervous system from the external environment is called external stimuli. External stimuli are factors which are detected by the body and communicated to the central nervous system such as temperature and scents.

Dysfunction of the nervous system does not contraindicate massage. My personal work involves working with the nervous system to release nerves and muscles. Active stimulation of the nerves, although painful, and with probable bruising, can improve nerve conductivity, increase mobilization, almost immediately restore range of motion, and is deeply appreciated by those who have grown familiar with the technique. I have seen rapid progress with those recovering from injury, suffering from MS, fibromyalgia, and loss of range of motion. If properly done it almost always alleviates pain within the hour.

It is not one of the cranial nerves (I-XII), it is cervical nerve number 6.

An adaptive-control system is the part of a control system which dynamically updates the parameters of an optimizing control function or direct control function.

Vagus Nerve disorder cannot so much be cured as it can be treated by medicines with positive effects. Medicines may be prescribed for short or long term use. Other treatments include exercises and surgery.

Hormones are distributed through the body by means of blood circulation, and it takes some time for a hormone that is secreted in one location of the body to diffuse through the blood sufficiently that it will reach some other specific location. In comparison, nerve impulses travel very quickly, almost instantaneously as far as our human time scale is concerned.
The nervous system responses are electrical while the hormonal responses have to be released into the bloodstream

The organs of the nervous system, including the brain, spinal cord, and nerves, work together to process and transmit information throughout the body. The brain serves as the control center, interpreting sensory input and coordinating responses. The spinal cord acts as a conduit for signals between the brain and the rest of the body, while nerves extend from the spinal cord to relay messages to and from various tissues and organs. Together, these components enable complex functions such as movement, sensation, and cognition.

Smiling is an action produce by more than one muscle but the nerve that allows you to do that is the facial nerve (7th cranial nerve). Facial nerve has 5 branches and the action of all 5 allows you to smile nicely. The temporal branch allow you to wrinkle your forehead, the zygomatic branch allows you to partially close your eyes, the buccal branch allow you to elevate your chin, and the marginal mandibular allow you to widen your mouth laterally.
