21
Q

Where does the spinal cord extend to and from?

A

From: foramen magnum (hole in skull)

To: L1 (after that its cauda equina)

22
Q

Where do sensory neurones enter the spinal cord through?

A

Through Dorsal Horns

23
Q

What is a Dorsal Root Ganglion (DRG)?

A

Cell body of a sensory neurone that it chucks outside the spinal cord before it enters

24
Q

Where do motor neurones leave the spinal cord from?

A

From ventral horns

25
Q

What is the central matter of the spinal cord?

A

Grey Matter = neuronal cell bodies

26
Q

What is the peripheral matter of the spinal cord?

A

White Matter = axons going up and down spinal cord, arranged into TRACTS with specific organisations

(e.g there is a pain tract)

27
Q

What are the layers of the head? (7 layers)

A
  1. Scalp
  2. Periosteum
  3. Skull
  4. Meninges
  • Dura Mater (Periosteal and Meningeal Dura Mater)
  • Arachnoid Mater
  1. Subarachnoid Space
  2. Pia Mater
  3. Brain

28
Q

What is the Falx Cerebri?

A

Internal extension of dura mater into middle of brain (between R and L hemispheres)

29
Q

What are the components of the brains ventricular system? (4 things)

A
  1. 2 Lateral Ventricles
  2. Third Ventricle
  3. Cerebral Aqueduct
  4. Fourth Ventricle
30
Q

What is the Choroid Plexus?

A

Plexus of cells that produces CSF

31
Q

Where is the Choroid Plexus found?

A

In all ventricles of the brain

32
Q

Where does the CSF from and to? (4 steps)

A
  1. Lat ventricles - foramina of monro → 3rd ventricle
  2. 3rd ventricle - cerebral aqueduct → 4th ventricle
  3. 4th ventricle - foramen of Luschka → subarachnoid space
  4. Travels rostrally over cerebral hemispheres → through arachnoid villi (granulation)→ dural venous sinuses
33
Q

What are the 4 main functions of the CSF? (4 things)

A
  1. Brain and spinal cord float in CSF → cause lightening of brain
  2. Cushions CNS → dampens effects of trauma
  3. Removes metabolites for CNS
  4. Provides stable ionic environment for CNS
34
Q

What is the arterial supply of the brain?

A

Circle of Willis

35
Q

What is the Circle of Willis?

A

Anastomoses of Internal Carotid Artery (ICA) and Vertebral Artery (VA)

AMPSAP

36
Q

What are the arteries supplying the Cerebral Cortex? (3 arteries)

A
  1. Anterior Cerebral Artery
  2. Middle Cerebral Artery
  3. Posterior Cerebral Artery
37
Q

What does the Anterior Cerebral Artery supply? (2 things)

A
  1. Medial Surface of Frontal + Parietal lobes
  2. Leg area of motor and somatosensory cortex
38
Q

What does the Middle Cerebral Artery supply?

A

Lateral surface of cerebral cortex

39
Q

What does the Posterior Cerebral Artery supply?

A

Inferior surface of brain

40
