Central Nervous System By Kyle Eaton

Dura Mater Location

Description: Dura Mater is the outermost and thickest layer of the meninges. It surrounds the brain and spinal cord.

Function: envelops the arachnoid matter. It surrounds and supports the dural sinuses which carry blood. It contains veins and is responsible for blood supply.

Fun Fact: it is nicknamed the "Tough Mother".

Dura Mater
Pia Mater Location

Description: The Innermost meninges layer. It is delicate

Location: It lines the skull and vertebral canal. It also encloses the brain and spinal cord.

Function: It acts as a protector of nerve tissue, supplies blood to the brain, and produces and circulates cerebrospinal fluid. It connects the CNS together and provides support.

Fun Fact: It´s nickname is ¨The Tender Mother¨

Gross! - A picture of each layer in real life!

Description: The middle layer of the meninges. It is described as delicate and looks like spider-webs. It contains the ¨subarachnoid space¨

Function: The reason for its unique web like structure is that Cerebrospinal fluid flows through it (the subarachnoid space)

Location: Between the other two layers. It is attached to the top of the dura mater.

Fun Fact: ¨Arachn¨ is the prefix meaning ¨spider.¨ It is called this because of the spider-web like appearance of the Arachnoid Mater.

Here is some real (gross) arachnoid mater.

The following lobes are parts of the Cerebrum

The cerebrum contains the lobes and Limbic System while the Cerebral Cortex contains only the lobes.

Contains the Frontal Lobe, Parietal Lobe, Occipital Lobe, Temporal Lobe, and the Insula.

Function: The frontal lobe is responsible for movement, abstract thinking, planning, and other logical functions.

Location: The front and top of the Cerebral Cortex

Function: The Parietal Lobe is responsible for interpreting the sense of touch. It is also responsible for taking in all sensory information and creating one sensation. Here's this old saying as an example; if it looks like a duck, walks like a duck, and sounds like a duck; its a duck.

Location: This lobe is above the Occipital Lobe, so it is on the top and second to furthest back.

Function: The Occipital lobe processes all information received from the eyes.

Location: The Occipital lobe is located at the back of the brain. Strangely it is found furthest from the eyes.

Fun Fact: "Occipital" means "back of the head". So like the Frontal Lobe, the Occipital Lobe has a very literal meaning!

Not so fun fact: Occipital tissue damage can cause visual hallucinations! Yikes!

A hallucination? I hope so...

Function: The Temporal Lobe is mainly responsible for processing auditory (hearing) and olfactory (smell) information. Interestingly enough, it is also responsible for emotion, language, and the formation of memories

Location: The Temporal Lobe is below the Frontal and Parietal Lobes.

Fun Fact: "Temporal" refers to time. Memories are of your past, so maybe that's the reasoning there? Huh. The more you know :O (I'm tired and babbling)

Function: Insula has a few different functions. First, Insula provides emotional context to go with our sensory information. The Insula also assists with control of motor functions such as swallowing and hand to eye coordination. The Insula also plays a part in regulating the body's immune system. Part of the insula processes the emotion "disgust."

Speculation: It is speculated that the Insula plays a role when it comes to empathy

Location: The Insula (Insular Cortex) is actually not very visible to the outside of the brain, this is because it is found deep within the lateral Sulcus.

The Location

Description: The large band of axons which connects the two brain hemispheres.

Function: Besides simply connecting the two hemispheres, the Corpus Callosum also carries messages from one to the other!

Otherwise known as "Primary Sensory Areas" (I believe)

Description: "The Sensory Cortex" contains the five major senses: (touch, taste, olfactory, auditory, visual).

Function: The somatosensory cortex receives all sensory information collected by the body, from there it is processed.

Simple version of the function: The part of the cerebral cortex responsible for recieving and interpreting sensory information. (From Dictionary.com)

(Also known as the "Sensory Speech Area")
Location of Wernickee's area

Function: Comprehension of language and is involved in language development

Location: Inside the temporal lobe on the left (dominant) side of the brain.

Fun Fact: "Wernicke's aphasia" refers to a condition in which a person has impaired comprehension of spoken language yet can speak fine.



Description: Part of the cerebral cortex.

Function: This part of the brain that links and assists coordination between sensory areas and motor areas

Trivia: It is the furthest developed area of the cerebral cortex and brain.

Many people make such art.
The left doesn't get enough credit or focus in my opinion.

Concept: The cerebral cortex is divided into the right and left hemispheres.

In humans, the left hemisphere is most often dominant. It controls logical thinking, is associated with language and speaking along with memory. It is considered to be the academic side of the brain.

The Right side of the brain is associated with creativity. It is also very importantly in change of spacial awareness.

IMPORTANT FACT: The left side of the brain controls the RIGHT side of the body and vice versa.


Description: It is composed of masses of gray matter. Middle part of the diencephalon.

Function: The Thalamus functions to regulate; motor control, conciousness + sleep cycle, and the senses. The Thalamus also chooses which sensory signals to relay to the appropriate brain area.

Location: It lies between the cerebral hemispheres.

Fun Fact: The sense that the thalamus does not relay information about is the sense of smell.



Function: The Hypothalamus regulates homestasis. Examples of this include coordinating the autonomic nervous system, controlling body temperature, controlling hunger and thirst, and regulating sleep.

Location: It is found below the thalamus.

Labeled Limbic System

Description: It is made up of nerves. It includes the hypothalamus, thalamus, and hippocampus among other parts.

Function: The structures included in this system are involved with motivation, emotion, and memory.

Location: It is located in the midline of the brain and near the Hypothalamus. Below the Thalamus.

Fun Fact: Damage to the brainstem can induce a coma! Yaaay!

Also known as the mesencephalon

Description: A small section of the brainstem. It connects the hindbrain to the forbrain.

Function: It manages the functions of the two hemispheres. It contains motor system pathways. It assists with movement and with processing visual and auditory information.

Location: It is below the cerebral cortex but above the hindbrain.

"Pons" is the singular version!

Description: Contains nuclei - deal with sleep and unconscious functions such as swallowing or breathing.

Function: It helps control breathing, communication within the brainm and controls sensations and senses. The Pons also regulates sleep.

Location: upper part of brainstem


Function: It assists with regulation of breathing, functions of the heart, sneezing, swallowing, and digestion. It functions as the center for respiration and circulation. for the brain.

Location: Below the Pons, in front of the cerebellum.

Background: Normally the heart beats without need of nervous system assistance/control. This is not the case when exercising.

Function: Responsible for regulating heartbeat.

Location: In the Medulla oblongata


Function: It regulates blood pressure and other such homeostatic processes.

Location: Below the hypothalamus.


Function: Controls the rate and amount of respiratory movements of the diaphragm.


Function: It takes in sensory information from sensory systems, the spinal cord, and other areas of the brain and regulates voluntary motor movements: balance, coordination, etc.

Its 2:00AM and I'm exhausted, so here are some brain puns.
These are pretty creative :)
