Nervous

• corpus callosum - connects right and left hemisphere
• Telencephalon - Cerebrum
• Telencephalon - Largest component of the brain
• Telencephalon - Made up of 2 hemispheres (left and right)
• White matter that connects/separates the left and right hemispheres
• CORTEX = OUTER
• Gyrus - ELEVATIONS
• Central sulcus - grooves between Frontol & pariental lobe
• Sulcus - GROOVES
• Fissures - DEEPER grooves
• cerebellum - coordinates voluntary movements, balance, posture, equilibrium
• medulla oblongata - controls involuntary functions such as heart rate, breathing, blood pressure, digestion, vomiting, sneezing, coughing, swallowing, salivation, yawning, hiccuping, vomiting, etc.
• spinal cord - transmits sensory information from the body to the brain and motor commands from the brain to muscles

• Lobes of cerebral cortex

  • frontal lobe
  • parietal lobe
  • temporal lobe
  • occipital lobe
• frontal lobe

  • pre central gyrus - primary motor cortex
  • brochas area - primary motor speech area
• temporal lobe

  • wernike’s area - sensory speech area and speech comprehension
• parietal lobe

  • postcentral gyrus - primary somatic sensory cortex
• occipital lobe

  • primary visual cortex - primary visual cortex
• Gray matter - cell bodies
• white matter - myelinated nerve fibers of axon
• central sulcus - grooves between frontal and parietal lobe
• Amygdala

  • almond shaped
  • fear, anger and arousal
• basal ganglia

  • group of subcortical nuclei that is responsible for motor control - caudate, putamen, globus pallidus, substantia nigra and subthalmic nucleus
• substantia nigra

  • contain inhibitory neuron that regulate voluntary motor control
  • neurons secrete dopamine as neurotransmitter
• Diencephalon

  • thalamus
  • hypothalamus
  • epithalamus
• thalamus - relay center of brain
• hypothalamus

  • communicate with the pituitary gland
  • regulate body hormones - body homeostasis
• epithalamus - pineal gland (important component)
• pineal gland

  • produce melatonin - regulate sleep
