Watching the brain light up
Watching the Brain “light up”

Neurologists and scientists who specialize in studying the brain can take pictures of the brain of a person who is involved in various activities.


“brain mapping.”

It is significant because it shows what part of the brain is active during certain activities or thought processes.

The spinal cord
The Spinal Cord

  • 31 pairs of nerves extending out from spinal cord

  • Correspond to nerve pathways that connect to various organs/systems

The nervous system1

The Nervous System by:

Pathological Conditions


Categories of pathological conditions
Categories of by:Pathological Conditions

Neurologists and Neurosurgeons

deal with many different kinds of problems

involving the brain and spinal cord.


Categories of pathological conditions1
Categories of by:Pathological Conditions

  • Most brain and spinal cord disorders are classified into one of the following categories:

  • Congenital disorders

  • Degenerative, functional and seizure disorders

  • Infectious disorders

  • Intracranial tumors

  • Traumatic disorders

  • Vascular disorders

  • Peripheral nerve disorders

  • Disk disorders


Disk Disorder by:

Example:

Degenerative disk

What is it? Deterioration of the intervertebral disk, usually due to constant motion and wearing on the disk.


Infectious Disorder by:

Example: Shingles (Herpes Zoster”

What is it? An acute viral infection involving inflammation of the spinal or cranial nerves that produces a painful skin rash.


Intracranial tumors (primary) by:

Example: Glioblastoma

Breakdown of word:

Gli/o- gluey substance

blast= embryonic stage

-oma= tumor

What is it? A malignant (cancerous) brain tumor that starts in the glial cells of the brain.


Congenital Disorder by:

Example: Anencephaly

Breakdown of word:

an- without, not

Encephal/0= brain

-y = (noun ending)

Characterized by the absence of the brain and spinal cord at birth.


Traumatic Disorder by:

Example:

Cerebral Concussion

What is it? A brief interruption of brain function caused by blunt trauma to the head.

http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000034.htm


Vascular Disorder by:

Example:Cerebrovascular Accident (CVA)

What is it? Death of part of the brain due to decreased blood flow to that area. Also known as “stroke.”

http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000123.htm


Peripheral Disorder by:

Example: Carpal tunnel syndrome

What is it? A pinched or compressed nerve in the carpal tunnel passage of the wrist.


Seizure Disorder by:

Example: Epilepsy

Breakdown of word:

Epi- over, upon

-lepsy= seizure, attack

What is it? A syndrome of recurring episodes of excessive irregular activity in the central nervous system.


Concept review and comprehension check1
Concept Review and by:Comprehension Check

What does the word Congenital mean?

(1) From birth

(2) A degenerative disorder

(3) A brief interruption of consciousness


  • Pain in the wrist

  • Problems that arise in the cerebral cortex

  • Problems that arise in the blood vessels to the brain


  • Carpal tunnel syndrome

  • Shingles (Herpes zoster)

  • glioblastoma


  • Low blood sugar

  • A car accident

  • Decreased blood flow to part of the brain
