What disease is this

Alexander Disease

What is Alexander Disease?

the mutation of GFAP genes that causes the overproduction of GFAP protein causing cell to fail.

Astrocytoma

Type of Cancer that form in the brain or spinal cord

What is Multiple Sclerosis?

autoimmune disorder, where the body attacks and damages the myelin sheath of its own nerves

 disrupts communication between the brain and body and causes symptoms such as vision loss, pain, fatigue, and impaired coordination.

\n

What nerve is effected by Multiple Sclerosis?

Oligodendrocytes

What is HIV/AIDS Encephalitis?

Viral-Activated Microglia produce neurotoxins such as glutamate and NO, which damage the brain

What is the Diagnosis?

Viral Activated Microglia

What is the Autonomic Nervous System?

The autonomic nervous system is the type of nervous system that activates when you panic

What is Coronal?

Separates the brain from front to back (Butterfly)

What Is this

What is Sagittal?

 Sagittal slices the brain down the midline and horizontal separates the brain from top to bottom.

What is this?

Sagittal

What is Horizontal?

separates brain from top to bottom

What is this?

Horizontal

Explain White Matter Vs Grey Matter

White Matter

• Composed Of an Axon bundle

• White because myelin sheaths cover the axon

Grey Matter

• Composed of clusters of neuron cell bodies

• have a dark grey appearance

What’s the Four Cortical lobes

Frontal

Parietal

Occipital

Temporal

What view is this?

Lateral

What view is this?

Horizontal

What is this diagnosis?

Subdural Hematoma

(Blood is in the subdural space but under the skull (underneath the dura)

What affects the speed that information is transmitted?

• Neuron diameter (thicker = faster)

• Myelin sheath (more myelin = faster)

• Number of neurons involved (fewer = faster)

What benefits is there with larger neurons?

• Can make more connections

• Can cover greater distances

• Transmit information faster
