Q

outline function of cerebellum

A

little brain (more neurons than those in rest of CNS)
coordinate visual, motor input, spinal cord info to output movements, balance

Q

explain role of cerebrospinal fluid

A

makes brain life, cushions sudden impacts to prevent brain damage. maintains appropriate ion levels (remove neuron byproduct and ensures enough oxygen, glucose)

Q

outline the structure/layout of ventricles in brain

A

1 lateral ventricle per cerebral hemisphere. meets in front, comes down to form 3rd above hypothalamus. come down narrow tube into 4th (if blocked = hydrocephalus) near pons, and move down into thin cavity (central canal) which follows down spinal cord center

17
Q

name 4 subsections of spinal cord

A
  1. cervical (+cervical enlargement)
  2. thoracic
  3. lumbar (+lumbar enlargement)
  4. sacral
18
Q

outline role of cervical spinal cord enlargement

A

lots of motor neurons for controlling arm/hand muscle, and allow high dexterity

19
Q

outline role of lumbosacral spinal cord enlargement

A

many motor neurons needed for controlling leg muscles

20
Q

what does grey/white matter tend to be made of

A

grey matter = neuronal cell bodies, glial cell
white matter = neuronal axons

21
Q

outline afferent and efferent fibres etc

A

afferent = sensory fibres coming into spinal cord
efferent = motor fibres leaving spinal cord

Dorsal
Afferent
Ventral
Efferent
