Q

Synapse?

A

The junction between neurons
Cell communication

19
Q

Postsynaptic nueron?

A

Receives neurotransmitter from other neuron

20
Q

Sodium order

A
  1. A graded depolarization brings an area of an excitable membrane to threshold.
  2. A temporary hyperpolarization occurs
  3. Sodium channels activation occurs
  4. Sodium channels are inactivated
  5. Sodium ions enter the cell and depolarization occurs
  6. Voltage gated potassium moves out the cell, initiating repolarization
  7. sodium channels regain normal properties
21
Q

Sodium channels blocked?

A

NO action potential

22
Q

What is needed for action potential?

A

Depolarization

23
Q

Reflex steps

A
  1. Info processing
  2. sensodru neurpn activation
  3. motor neruron activation
  4. Sensory receptor activation
  5. Effector response
24
Q

White matter

A

Myelinated axons in tracts (bundles of nerve fibers)

25
Q

Grey matter

A

Unmyelinated cell bodies

26
Q

Parts of brain stem

A
  1. Midbrian
  2. Pons
  3. Medula Obligata
27
Q

Sodium pump function

A

Uses ATP to restore ion concentrations to their original state

28
Q

Reason a reflex response may fail during a clinical exam?

A
  1. Nerve damage, nerve conduction issue, consciously supress response, CNS damage
29
Q

Cerebral spinal fluid flows in what location?

A

Subarachnoid space

30
Q

Cerebrospinal Fluid Function?

A

Transport weight and nutrients, cushion

31
Q

Gyri

A

Elevated ridges (on brain)

32
Q

Sucli

A

Shallow grooves (on brain)

33
Q

A

Acute inflammation of the meniges

34
Q

Meningitis causes

A

Bacterial Infection
Vital

35
Q

Nervous Tissue Wrapping

A

Endoneurium: surrounds
each neuron

Perineurium: surrounds a
group of
neurons or
fascicle

Epineurium:
surrounds a
nerve

36
Q

Order of meninges

A
  • Dura mater

Mood swings
Thirst and Hunger changes

40
Q

Disorder

A

damaged substainia nigra and decrease dompamine

41
Q

Seizure

A

Temporary cerebral ex disorder with abnormal movements, weird senations, and inappropriate behavior

42
Q

3 protective structures

A
  1. Bones- hard protection around vital structures
  2. Cerebral fluid- cushion
  3. Meniges- provide protective layers
43
