Study Notes
Nervous System & Mental Health Terminology
- esthet/o: Refers to sensation or feeling, crucial in understanding sensory nerves.
- encephal/o: Denotes the brain, central to the nervous system's function.
- contus/o: Indicates a bruise, important in diagnosis of traumatic brain injuries.
- psych/o: Relates to the mind, a key term in psychiatry and psychology.
- concuss/o: Means shaken together, relevant in concussion and traumatic injuries.
- mening/o: Signifies the membrane that covers the brain, essential for understanding protective layers.
- -graphy: Refers to the process of producing a picture, utilized in various imaging techniques.
- -esthesia: Involves sensation or feeling, often used to describe sensory disorders.
- myel/o: Pertains to the spinal cord, vital in the context of nervous system connectivity.
- radicul/o: Refers to nerve roots, crucial in understanding nerve function and condition.
- -phobia: Indicates an abnormal fear, relevant in mental health diagnoses.
- caus/o: Signifies a burning sensation, often related to nerve damage.
- cerebr/o: Refers closely to the brain, particularly the cerebrum, which is the largest brain region.
- neur/o: Indicates nerve, foundational in neurological terminology.
- -tropic: Means having an affinity for, often used in discussions of hormones affecting target organs.
Nervous System Structures and Functions
- Synapse: The junction between two neurons or between a neuron and a receptor, important for signal transmission.
- Myelin sheath: Protective covering over nerves, enhances signal speed.
- Dendrites: Receive impulses and conduct them toward the cell body; critical for information processing in neurons.
- Pia mater: Innermost layer of the meninges, closely adheres to the brain and spinal cord, plays a protective role.
- Hypothalamus: Regulates key body functions such as temperature, hunger, and sleep cycles.
- Sympathetic nerves: Part of the autonomic nervous system, prepares the body for stress responses.
- Plexus: A network of intersecting nerves, important for nerve functionality and pathways.
- Peripheral nervous system: Includes cranial and spinal nerves, extends beyond the central nervous system.
- Thalamus: Acts as a relay station for sensory information to the cerebral cortex.
- Efferent neurons: Responsible for transmitting impulses away from the brain and spinal cord to effectors.
Brain Regions and Their Functions
- Brainstem: Connects the brain to the spinal cord, controls basic life functions.
- Hypothalamus: Coordinates functions including hormone release and autonomic nervous system activity.
- Cerebellum: Important for muscle coordination and balance.
- Medulla oblongata: Controls essential functions like breathing and heart rate.
- Cerebrum: Houses higher-level functions such as reasoning, emotions, and voluntary motor activities.
Psychological Conditions and Disorders
- Coma: A state of profound unconsciousness; no spontaneous movement or responsiveness.
- Hallucination: Sensory perceptions without an external stimulus, significant in various mental health disorders.
- Acrophobia: An intense fear of heights, a common type of anxiety disorder.
- Anxiety disorders: Characterized by excessive and irrational fears affecting daily life.
- Bipolar disorder: Involves mood swings between highs and lows impacting behavior and energy levels.
- Alzheimer's disease: A degenerative disorder affecting memory and cognitive function.
- Insomnia: Persistent difficulty in sleeping; critical for overall health.
- Anorexia nervosa: An eating disorder characterized by an intense fear of gaining weight leading to severe food restriction.
- Epilepsy: A neurological disorder characterized by recurrent seizures.
Key Medical Terminology & Definitions
- Cerebral palsy (CP): A movement disorder caused by damage to the brain, usually at or before birth.
- Cerebrospinal fluid (CSF): Fluid that cushions the brain and spinal cord, important for central nervous system protection.
- Obsessive-compulsive disorder (OCD): Characterized by unwanted and intrusive thoughts followed by compulsive actions.
- Transient ischemic attack (TIA): A temporary period of symptoms similar to those of a stroke; a warning sign for potential strokes.
- Hydrocephalus: Abnormal accumulation of cerebrospinal fluid in the ventricles, leading to increased intracranial pressure.
- Neuroma: A benign tumor comprising nerve tissue, relevant in nerve damage and pain assessment.
