• pre central gyrus


  Responsible for voluntary motor movement
• Acetylcholine is a neurotransmitter that plays a crucial role in muscle movement, learning, and memory.
• Dopamine is a neurotransmitter involved in reward-motivated behavior and motor control.
• The prefrontal cortex is the part of the brain responsible for executive functions such as decision-making, planning, and impulse control.
• Cerebrum controls conscious thought processes such as emotions, decision making, memory, special senses, movement.
• • Diencephalon is split into the hypothalamus( controls hormones, body temp) and thalamus (relays sensory info like sleep cycle)
• Mesencephalon processes visual and auditory data
• Medulla oblongata relays sensory information to thalamus. It is responsible for autonomic centers: cardiovascular, respiratory, and digestive system activities/vitals
• Cerebellum coordinates balance and posture
• Longitudinal fissure separates cerebral hemispheres
• lateral fissure separates frontal and temporal lobe
• Cerebral veins are covered by arachnoid meninges (spider weblike)
• Dura mater is the outermost layer of meningeal membranes that surround the brain and spinal cord.
• Gyrus is the elevated ridge of tissue. Sulcus are shallow grooves. Both separate brain areas and increase surface area of cerebral cortex.
• Postcentral gyrus is responsible for somatosensory processing like touch, pressure, pain, temperature
• central sulcus separates frontal and parietal lobe
• parieto-occipital sulcus separates parietal from occipital
• cerebral spinal fluid circulates within the ventricles of the brain
• there are four ventricles: 2 lateral ventricles, third ventricle, and fourth ventricle
• what are the neurotic cells that line the ventricles to make cerebral spinal fluid?

  ependymal cells
• A neuroglial cell that is a major component of blood-brain barrier is the astrocyte
• What organs are supplied by the internal carotid artery?

  The internal carotid artery supplies the eyes and brain with blood
• What organs are supplied by the vertebral artery?

  The vertebral artery supplies the head, neck, and brain with blood
• What is the vermis?


  median portion of the cerebellum that connects two hemispheres
• Arbor vitae is the white matter of the cerebellum
• Optic chasm- part of brain where optic nerves cross to enable vision for both eyes
• septum pellucid separates left and right lateral ventricles
• Pineal gland controls nocturnal rhythm
• Mamillary body controls feeding reflexes
• corpus callosum coordinates left and right side of the brain
• primary motor cortex (pre central gyrus): located in the frontal lobe, responsible for voluntary movement (contralateral side). If looking at the left lateral surface of the brain, the left primary motor controls movement oof the right side
• Premotor cortex: A region of the frontal lobe that is involved in planning and initiating voluntary movements.
• Prefrontal cortex: Involved in planning, problem solving, and decision making.
• gustatory cortex: taste receptors in the mouth, taste buds, taste nerve fibers
• auditory cortex is located in the temporal lobe and is responsible for processing auditory information. ex: awareness of sound and pitch
• auditory association area: analyzes and recognizes sound
• olfactory cortex: awareness of smell
• primary sensory cortex (post central gyrus): awareness of somatic sections
• somatic sensory association area: receives sensory information from skin, muscles, joints, and tendons. draws back from memories to interoperate sensations
• visual cortex is located in the occipital lobe and is responsible for awareness of vision
