Welcome to The School of The Nervous!

Here you'll learn all about the Nervous System and how it works within our bodies. We will be focusing mostly on the spinal cord, spinal nerves, and the spinal reflexes.

To make sure you have your schedule and the main control center of the school that makes sure everything is running smoothly is administration!

In the body this would be the Central Nervous System or the CNS. The CNS is the brain and spinal cord in the body which is the powerhouse or command center of the nervous system!

To assist with the the administration's orders, we have the rest of the school's staff, such as teachers and janitors, to carry them out and deliver sensitive information about the student body to the administration.

In the body, this would be the Peripheral Nervous System, or the PNS. The PNS encompasses all neural tissue outside the CNS, deliver sensory info, and carries motor commands to peripheral tissues and systems in the body.

The Spinal Cord!

The Guidance Counselours are each people apart of the administration that support the school and give all the students their scaffolding and schedules to go about their day.

In the body, the spinal cord supports the body that are made up of different segments where nerves exit, either sensory or motor information.

The Spinal Cord (Continued)

-About 18 inches from cranium to L1 and L2

-It becomes enlarged at the cervical enlargement of .3 to .55 inches.

-divided into 31 segments with nerves branching off which exit off the forame

-The lumbar enlargement gives nerves to the legs

White and Gray Matter

The Spinal Cord is made up of two types of matter; the white and gray matter. The gray matter is made up of unmyelinated tissue, and is used to process the spinal reflexes. The white matter is superficial to the gray matter, and is made up of myelinated axons. It acts as relay paths to send signals. The ascending tracts are in charge of carrying sensory information to the brain, and the decending tracts bring the motor commands to the spinal nerves, to then be bought to the muscles and glands. In a school setting, the gray matter acts as the computers that are used for scheduling and other documented information. The mail substitues the white, as it sends the schdudels and notes to the parents, just like sending the sensory information and motor commands.

Spinal Nerves:

The spinal nerves transport both sensory and motor information. They are numbered the same as the vertebrae. For example, the second nerve down the neck would be C2 and the eleventh nerve down the chest would be T11. The distal end of the spinal cord are called cauda and equina and look similar horses tails.

In the school, this would resemble the students! the students are the ones that carry out the information that comes from the teachers and guidance counselors

Spinal Nerves (continued):

The Dorsal roots nerves are the sensory neurons which detect external elements like touch, pain, temp etc.

The Ventral roots are motor nerves which take the impulses and gives commands to the body.

Spinal/Cranial Meninges

The meninges around the spine and brain are nothing more than a protective membrane that carries blood and isolates the spine/brain from its surroundings. The spinal and cranial meninges are continous with each other, meaning the cooperate with each other all the time.

In the school, the interactions set of the assistant principal to meet the guidance counselors would be akin to the meninges as it protects the fulfillment of an objective and isolates them from any stress.

Each Major Plexus

A nerve plexus consists of roots of adjacent nerves formed into a complex web, allowing for nerve impulses to travel through pathways that overlap each other. There are four major types; the cervical, consisting of the neck, the brachial, including the arms and some neck, and the lumbar and sacral plexus, made up of the lower back, pelvis, and legs. The nerve plexus is similar to the overpasses in Medford High, as they overlap each other and allow for a pathway for students to get from class to class.

Four Examples Of Nerves In The Body:

1.The phrenic nerve is the nerve that comes off the neck from C3 to C5 and controls breathing by receiving and sending information from the diaphragm.

2.The femoral nerve branches off the lumbar plexus and controls the muscles that straighten the leg.

3.The sciatic nerve branches from the lower back into either legs. It provides the connection of the body to the nervous system.

4.The ulnar nerve branches contract to move hand muscles and branches of the cervical plexus.

Spinal Reflexes

In the body, the spinal reflexes occur by a specific stimuli, are nerve responses that are both lighting fast and automatic, and are controlled by the spinal cord as opposed to the brain.

In the school, when an emergency occurs, the guidance team/nurses quickly respond to the situation as opposed to the assistant principles.

Overview of the Brain

There are three regions that make up the brain; the cerebrum, cerebellum, and the brain stem. The cranium and the same meninges and CDF as the spinal cord engulf the brain, serving to protect and control the brain's chemical environment. The cerebrum The brain stem connects the brain to the spinal cord, processing information being sent to the brain. The largest part of the brain is known as the cerebrum, in charge of your intellectual abilities and conscious thoughts. The cerebellum is in control of small movements to adjust your posture and body position subconsciously.

Overview of the Cerebrum

The Cerebrum is the biggest part of the brain which manipulates all conscious thoughts and intellectual functions and processing somatic sensory and motor related data.

Corpus Callosum - The nervous fibers that connect the two hemispheres of the brain.

Cerebral Cortex - A folded layer of gray matter on surface of hemisphere.

Contra Lateral - The concept that each cerebral hemisphere receives sensory info and sends motor commands to the opposite side of the body.

Analogy of the Cerebrum with respect to the School:



At the School for the Nervous, it could be said that the student handbook is analogous to the cerebrum as it contains all of the rules to act by and details written procedures of what to do when some regular/extraneous event occurs and how to respond to said event.

Two Motor Areas of the Cerebral Cortex:

-The primary motor cortex controls all voluntary movement.

-The Premotor Cortex coordinates motor responses like learned movements or muscle memory.

In the school, these would represent the students schedules that tell them where to move or where to go within the school.
