The brain is split into three regions |
1) Cerebrum/Cerebral Cortex 2) Cerebellum/ Cerebeller Cortex 3) Brain Stem |
|
The Brain is also split up a different way, these sections each have specific functions |
1) Forebrain 2)Midbrain 3) Hindbrain |
|
The Central Nervous System includes these organs: |
1) Brain 2) Spinal Cord |
|
The Forebrain contains: |
Embryonic Developments: 1) Telencephalon 2)Diencephalon Parts: Cerebral Cortx, Basil Ganglia, Limbic System, hypothalmus, and thalmus. |
|
The Midbrain contains: |
Embryonic Structures: Mesencephalon Parts: Tectum and Tegmentum |
|
Hindbrain contains: |
Embyronic Sturctures: Metencephalon and Mylencephalon Parts: Cerebellum, Medulla, and pons. |
|
Coronal Plane |
Cut parallel to the face |
|
Sagaittal Plane |
Cut right down the middle of the brain. ex: mid sagittal, paralateral-next to the mid line/mid sagittal |
|
Horizontal Plane |
Parallel with the floor. |
|
Rostral |
"Towards the beak", the front part of the brain |
|
Caudal |
Towards the Back |
|
Ventral |
The bottom |
|
Dorsal |
Top |
|
Nucleus |
Consists of neuronal cell bodies, dendrites, and gilia. Can be made into sheets, for ex, the cortex of the brain. ***CONTEXT OF THE BRAIN! NUCLEI OF THE BRAIN DO NOT CONTAIN DNA!*** |
|
Tract |
a pathway in the brain that is made up of neurons of the same origin and axons. They all have a similar destination they need to go to. (thus making a tract.) * They're Mylenated* Tract names are base on their origin and their direction. |
|
Afferent |
Projecting toward the brain |
|
Efferent |
Projecting away from the brain (ie motor cortex) |
|
Dessucate |
Cross over to the oppisite side |
|
Systems are ___ |
1) Complex organazations of many organs the focus on one (or many) goals. Ex: motor, visual, somasensory, etc. |
|
Grey Matter |
Neuronal somas that are arranged into nuclei or cortex |
|
White Matter |
Made up of myelinated and unmylinated axons. |
|
Myelin |
Myelin is made by oligodendrocytes that speed the process of eletrical messages down the neuronal axon. |
|
Diencephalon cantains the |
thalmus and hyperthalmus |
|
What is a cluster of neuronal somas in the peripheral nervous system called? |
ganglion |
