    • Course: BIOL117
    • Institution: East Stroudsburg University
    • Topics: Introduction to the CNS, Structure & Function of the Brain, Cranial Nerves

    Neuron Structure

    • Soma (cell body): Contains the nucleus and other organelles
    • Neuroplasm: Cytoplasm of the neuron
    • Nucleus: Control center of the neuron
    • Axon hillock: Cone-shaped region of the neuron where the axon begins
    • Axon: Long, slender projection that transmits signals away from the soma
    • Dendrites: Short, branching projections that receive signals from other neurons
    • Schwann cells: Wrap around axons to form myelin sheaths
    • Nodes of Ranvier: Gaps in the myelin sheath
    • Meninges: Protective membranes surrounding the brain and spinal cord - Skull: Outermost protective layer - Dura mater: Tough, outer meningeal layer - Subdural space: Space between the dura mater and arachnoid mater - Arachnoid mater: Delicate, web-like meningeal layer - Subarachnoid space: Space between the arachnoid mater and pia mater - Pia mater: Delicate, inner meningeal layer

    Regions of the Brain

    • Forebrain: Divided into telencephalon and diencephalon
    • Midbrain: Mesencephalon
    • Hindbrain: Divided into metencephalon and myelencephalon

    Brain Lobes

    • Frontal Lobe: Precentral gyrus (primary motor cortex), planning, memory, social judgment, critical & creative thinking
    • Parietal Lobe: Postcentral gyrus (primary somatosensory cortex), receiving and interpreting sensory information, taste
    • Occipital Lobe: Visual center of the brain, depth perception, color, shape, vision recognition
    • Temporal Lobe: Hearing, smell, learning, memory, emotion

    Sulci/Fissures

    • Central Sulcus: Separates the frontal and parietal lobes
    • Lateral Sulcus: Separates the frontal, parietal, and temporal lobes

    Deep/Mid-Sagittal Structures of Brain

    • Corpus callosum: Connects the cerebral hemispheres
    • Thalamus: Relay station for sensory information
    • Hypothalamus: Regulates homeostasis, endocrine function
    • Pituitary Gland: Endocrine gland

    Cranial Nerves

    • 12 pairs of cranial nerves
    • Sensory, motor, or both
    • Memorize the functions and whether they are sensory or motor

    Important terminology/concepts

    • Grey matter: Primarily cell bodies and dendrites
    • White matter: Primarily axons
