    Study Notes

    • cerebr/o: Refers to the cerebrum, the largest and uppermost portion of the brain.
    • crani/o: Denotes the cranium, commonly known as the skull.
    • encephal/o: Represents the brain, the central organ of the nervous system.
    • gangli/o: Indicates a ganglion, which is a knotlike mass of nerve cells located in the peripheral nervous system.
    • gli/o: Signifies neuroglial tissue, often referred to as "glue" in the nervous system.

    Movement and Function Terms

    • kinesi/o: Relates to movement, essential for physical activity and function.
    • sthen/o: Refers to strength, significant in muscle function.

    Additional Anatomical Terms

    • mening/o, meningi/o: Refers to the meninges, the membranes that cover the brain and spinal cord (two spellings).
    • myel/o: Denotes both bone marrow and spinal cord, crucial for hematopoiesis and nerve signal transmission.
    • poli/o: Indicates gray matter, which is made up of neuronal cell bodies in the brain and spinal cord.
    • thalam/o: Refers to the thalamus, an important part of the diencephalon that processes sensory information.

    Suffixes Indicating Conditions and Symptoms

    • -lysis: Indicates separation, destruction, or loosening in medical terminology.
    • -algia, -algesia: Both denote pain, used in various medical conditions.
    • -asthenia: Refers to weakness or debility, indicating reduced strength or energy.
    • -esthesia: Signifies feeling or sensation.
    • -kinesia: Relates to movement, often used in combination with other terms to describe movement disorders.
    • -lepsy: Indicates seizure activity, often seen in neurological terms.
    • -paresis: Signifies partial paralysis, a condition impacting voluntary movement.
    • -phasia: Refers to speech, with variations indicating different speech difficulties.
    • -plegia: Denotes paralysis, a complete loss of movement in affected areas.
    • -taxia: Indicates order or coordination, important in understanding neurological function.

    Disorders and Conditions

    • synalgia: Describes referred pain, where discomfort is felt in a location different from the source.
    • neuralgia: Identifies pain in a nerve, often debilitating and challenging to manage.
    • dyskinesia: Refers to painful or difficult movements, often associated with neurological disorders.
    • dysphasia: Indicates difficulty in speech, which may arise from brain injury or stroke.
    • aphasia: Represents a total lack or loss of ability to speak, typically resulting from brain damage.
    • radiculopathy: Identifies inflammation of the nerve root, also known as radiculitis, impacting nerve function.

    Prefixes Indicating Relative Position or Condition

    • pachy-: Indicates thickness, often used in relation to tissues.
    • para-: Means near, beside, or beyond, often used in medical context to describe adjacent structures.
    • syn-: Signifies union or being joined together, important in describing joint actions or associations.

    Stroke Types

    • ischemic: Refers to a type of stroke caused by narrowing of carotid arteries, leading to reduced blood flow to the brain.
