  • Gray matter

    Regions of clustered neuron cell bodies within the CNS.

  • White matter

    Tracts of axons within the CNS.

  • reflexes

    An automatic reaction to a stimulus, mediated by the spinal cord or lower brain

  • Motor system

    Motor system: Controls movement of your muscles. 💪

    👉 Easy: “Controls body movement.”

  • Autonomic system

    Controls automatic body functions you don’t think about.

    👉 Easy: “Controls things your body does automatically.”

  • enteric nervous system

    Controls digestion in your gut. 🥗

    👉 Easy: “Controls digestion.”

  • Sypathaic Division

    Part of the autonomic nervous system that prepares your body for action or stress.

    👉 Easy: “Fight or flight.” ⚡🧠

  • Parasympathetic division:

    Part of the autonomic nervous system that calms the body and helps with rest and digestion.

    👉 Easy: “Rest and digest.” 😌🧠

  • Forebrain

    The largest and most developed part of the brain. It controls thinking, emotions, memory, sensory processing, and voluntary movement.

    👉 Easy: “Thinking, feeling, sensing, and moving.” 🧠

  • MidBrain

    The part of the brain that helps control movement, vision, hearing, and alertness.

    👉 Easy: “Movement, senses, and alertness.” 🧠⚡

  • Hindbrain

    The part of the brain that controls basic life functions like breathing, heart rate, balance, and coordination.

    👉 Easy: “Keeps you alive and coordinated.”

  • Brainstem:

    The part of the brain that connects the brain to the spinal cord

  • Cerebrum

    The largest part of the brain, responsible for thinking, memory, language, senses, and voluntary movement.

    👉 Easy: “Thinking, memory, senses, and movement.” 🧠⚡

  • cerebral Cortex

    The thin outer layer of the cerebrum that controls thinking, perception, memory, language, and voluntary movement.

    👉 Easy: “Outer layer for thinking and processing.”

  • Corpus callosum:

    A thick bundle of nerve fibers that connects the left and right hemispheres of the brain, allowing them to communicate.

    👉 Easy: “Connects the two sides of the brain.” 🧠↔️🧠

  • Diencephalon

    A part of the forebrain that helps control sensory information, emotions, movement, and basic body functions. It includes the thalamus and hypothalamus.

    👉 Easy: “Relays senses and controls body functions.” 🧠

  • Biological Clock

    An internal system that controls daily body rhythms, like sleep, wakefulness, and hormone release.

    👉 Easy: “Your body’s 24-hour timer.” ⏰🧠

  • Suprachiasmatic nucleus (SCN)

    : A small group of cells in the hypothalamus that acts as the body’s main biological clock, helping control the sleep-wake cycle.

    👉 Easy: “The brain’s main body clock.” ⏰🧠

  • Amygdala

    A brain structure involved in processing emotions, especially fear, threat, and emotional memories.

    👉 Easy: “Controls strong emotions, especially fear.” 🧠⚡

  • lateralization

    The idea that some brain functions are mainly controlled by one side (hemisphere) of the brain.

    👉 Easy: “Some functions are stronger on one side.” 🧠↔️🧠

  • neuronal plasticity

    The capacity of a nervous system to change with experience.

  • Short-Term Memorry

    The ability to hold information, anticipations, or goals for a time and then release them if they become irrelevant.

  • Long Term Memory

    The ability to hold, associate, and recall information over one’s lifetime.

  • Long term extesion

    (LTP) An enhanced responsiveness to an action potential (nerve signal) by a receiving neuron.
