neuroanatomy 1

• fill in the blanks

  A) superior

  B) rostral

  C) posterior

  D) inferior

  E) ventral

  
• what three main parts make up the brain?

  cerebrum

  cerebellum

  brain stem
• the brain - consists of two hemispheres: left and right

  Receives a constant flow of blood
• Contralateral - opposite sides
• Ipsilateral - same side
• fill in the blanks

  A) medial

  B) lateral

  
• fill in the blanks

  A) frontal

  B) parallel to the ground

  C) sagittal

  
• grey matter (darker regions) - made up of cell bodies and dendrites
• white matter (lighter regions) - made up of myelinated axons
• corpus collosum - collection of fibres that collect the two hemispheres
• meninges - 3 layers of tissue that protect the CNS
• Cerebrospinal fluid (CSF) - clear liquid that fills the subarachnoid space (brain cushioned by liquid)
• what are the functions of cerebrospinal fluid?

  buoyancy and waste management
• ventricular system - ventricles are hollow cavities filled with CSF
• cerebral cortex - outer surface of the cerebrum
• how is the cerebral cortex specialised to allow for a bigger surface area and more neurons?

  it's folded
• what are the functions of the frontal lobe?

  motor + cognition
• what are the functions of the temporal lobe?

  hearing, vision, cognition, emotion
• what re the functions of the parietal lobe?

  somatosensory
• what are the functions of the occipital lobe?

  vision

  A) frontal

  B) parietal

  C) temporal

  D) occipital

  E) cerebellum

  
• fill in the blanks

  A) primary motor cortex

  B) primary somatosensory cortex

  C) primary visual cortex

  D) primary auditory cortex
