Q

space between the arachnoid mater and pia mater

A

Subarachnoid space

19
Q

thin, highly vascularized, loose connective tissue; pia and ependyma that gives rise to the choroid plexus

A

Tela choroidea

20
Q

plexus of epithelial cells that produces the CSF in the ventricles of the brain
* T shaped

A

Choroid Plexus

21
Q

Blood supply of Choroid plexus of the lat. & 3rd ventricles

A
  1. choroidal branches of the internal carotid artery
  2. basilar artery
22
Q

Blood supply of choroid plexus of the 4rth ventricle

A

PICA of VA

23
Q

Blood supply of venous blood drains into

A
  1. Internal cerebral veins
  2. The great cerebral vein drains onto the inferior sagittal sinus
24
Q

clear, colorless fluid found in the ventricles and subarachnoid space around the brain and SC

A

CSF

25
Q

Where can you find csf?

A

Ventricles, SA, Ependymal & pial surfaces

26
Q

What produces CSF?

A

Choroid Plexus

27
Q

It cushions and protects the CNS from trauma

A

CSF

28
Q

It provides mechanical buoyancy and support for the brain

A

CSF

29
Q

It nourishes the CNS

A

CSF

30
Q

It removes metabolites CNS

A

CSF

31
Q

It serves as a pathway for pineal secretions to reach the pituitary gland

A

CSF

32
Q

Where is choroid plexus of the ventricle cavities’ formed?

A

Lateral ventricle (3rd&4th)

33
Q

Movement of CSF inside the ventricle is controlled by the:

A
  1. pulsations of the artery(choroid plexus)
  2. aid of the cilia and microvilli(ependymal cells)
34
Q

further movement of CSF is reliant on several factors which are

A
  1. pulsations of spinal arteries
  2. movement of the vertebral column
  3. respiration
  4. coughing
  5. changing body positions
35
Q

It serves as valves: when CSF pressure greater than venous pressure, absorption of the CSF occurs

A

Arachnoid Villi

36
Q

Absorption of CSF

A
  • some CSF absorbed directly into the veins in SA space
  • some CSF absorbed through lymphatic vessels
37
Q

Where does the SA extends?

A
  • around optic nerve to the back of the eyeball
  • cranial and spinal nerves
  • perineural lymph nodes
  • arteries and veins of the SC
  • SA space
38
Q

Where does the CSF flows through?

A

Intraventricular foramina of 3rd ventricle

39
Q

Other term for Blood Brain Barrier (BBB)

A

Blood Brain Spinal Cord Barrier

40
Q

free passage of water, gases, and lipid soluble substances from blood to CSF

A

Blood Cerebrospinal Fluid Barrier

40
Q

Structures that separate CSF from nervous tissue:

A
  • pia covering brain and SC
  • astrocytic foot processes
  • perivascular extensions of the SA space
  • ependymal surface of the ventricles
41
Q

derived from the Greek word “hydro” meaning water and “cephalus” meaning head

A

Hydrocephalus

42
Q

excessive accumulation of fluid in the brain

A

Hydrocephalus
