Side ASide B
Forebrain (or cerebrum)
2 Large cerebral hemispheres (left and right) Outer portion has thin covering (cortex)
Just above hindbrainIncludes: Clusters of sensory and motor neurons. Connect higher and lower of nerv system. Important relay for visual and auditory
Includes: brain stem, cerebellum, medulla
L: Above midbrainF: Switchboard, organizes input from sense organs and routes them. Sense have relay stations in thalamus.
Pons (bridge in Latin)
L: Hindbrain - just above medullaF: Carries nerve impulses between higher and lower levels of nerv system. Cluster of neurons which regulate sleep and involved with dreaming....
L: Hindbrain - first structureF: Regulates vital functions such as breathing and circulation, they occur automatically. Also two-way through fare for all sense and...
Cerebellum (little brain in Latin)
L: Hindbrain - rear of brain stem F: Muscular movement also some role in learning and memory. Regulates complex movement. Easily disrupted by alcohol.
L: Under thalamusF: Basic bio drives, sexual behaviour, temperature, eating, drinking, aggression and expressing emotion. Controls pituitary gland
Pituitary gland
Regulates growth: controls thyroid, ovaries, or testes, regulates metabolism. "Master gland"
Limbic System
L: Deep within cerebral hemiF: Important partner with hypothal, coordinate behav. needed to satisfy motivational and emotional urgesTWO PARTSHippocampus - forming and...
Reticular Formation
L: Buried in midbrain, finger shapedF: Alerts higher centers messages are coming then blocks or allows. Without messages don't register in conscious awareness....
Frontal Lobe
Speech and skeletal motor functions
Broca's Area
L: Temporal LobeF: Normal speech production, formulates then sends to motor cortex.
Temporal Lobe
Auditory system
Motor Cortex
L: Rear of Frontal LobeF:600+ muscles involved with voluntary , each hemisphere control opposite side.
Somatosensory Cortex
L: Parietal Lobe, just behind motorF: Sensory input that gives rise to our sensations (heat, touch, cold, and balance/body movement) Sends to opposite side
Parietal Lobe
Body sensation
Occipital Lobe
Wernicke's Area
L: Temporal LobeF: Language comprehension.
Frontal Lobe (Human difference)
L: FrontF: Plan and carry out a sequence of actions. Emotional experiencePrefrontal cortex - goal setting, planning, and judgement.
Corpus Callosum
Connects left and right hemispheres, neural bridge.
Basal Ganglia
L: Midbrain - surrounds thalamusF: Critical for voluntary motor control. More deliberate movements than cerebellum.
Cerebral Cortex
Grey stuff around outside. Not essential for living but needed for human quality of living
Association Cortex
Within all lobes. Highest level of mental function.
