Medical Terminology Ch. 10 The Nervous System Day 1
Agenda: Ch. 10 Lesson 1 • Objective: The student will be able to: • 1) Describe the structures AND define terms related to the diagnostic procedures of the nervous system • 2) Describe anesthesia/neurology specialties • Lesson: Ch.10 The Nervous System • Quiz 10 Monday, May 12th (A-day) or Tuesday, May 13th (B-day)
Brain • Encephal/o and Cerebr/o • Coordinates all activities of the body by receiving and transmitting messages throughout the body. • Cerebrospinal Fluid • Fluid that cushions and nourishes the brain and spinal cord • Note: Cephal/o • Head
Meninges • Mening/o
Spinal Cord • Myel/o • Transmits nerve impulses between the brain, limbs, and lower part of the body.
Nerves • Neur/o • Receive and transmit messages to and from all parts of the body. • Myelin Sheath • Protective covering of the neuron • Neurotransmitters • Chemical substances that make nerve impulse transmission possible
Diagnostic Procedures • Carotid Ultrasonography • process of using sound to take a 3D picture of the carotid arteries to determine blood flow and plaque build-up • Echoencephalography • process of using sound to take a 2D picture of the brain structures
Diagnostic Procedures • Electroencephalography • Myelography
Medical Specialty: Anesthesia • Types of Anesthetics • Local- directly affects the surgical site • Ex: minor dental procedures (cavity fillings) • Regional- affects the area around major nerves (larger, but limited body area) • Ex: Epidural Anesthesia • General- affects the brain and entire body • Ex: major surgery (requires assistive breathing device)
Epidural Anesthesia • Anesthesia produced from injecting an anesthetic into the epidural space of the spinal cord • Ex: childbirth
Medical Specialty: Anesthesia • Anesthesiologist • Physician • Anesthetist • Registered Nurse
Medical Specialty: Neurology • Neurologist • Neurosurgeon
Individual Activity • Complete Ch.10 Learning Exercises (day 1)
Review & Looking Ahead… • Discussed: The structures AND define terms related to the diagnostic procedures of the nervous system and anesthesia and neurology specialties. • Next class topic: Terms related to neurology. • Quiz 10 Monday, May 12th (A-day) or Tuesday, May 13th (B-day)
Medical Terminology Ch. 10 The Nervous System Day 2
Thought for the Day… Warm-up Thought for the Day & Warm-up Warm-Up B http://padlet.com/wall/CHSHS13
Agenda: Ch. 10 Lesson 2 • Objective: The student will be able to understands terms related to neurology. • Lesson: The Nervous System • Medical Specialty: Neurology (continued) • True Life: “I Have a Traumatic Brain Injury” • Quiz 10 Monday, May 12th (A-day) or Tuesday, May 13th (B-day)
Pathology of the Brain & Spinal Cord • Migraine Headache • Throbbing pain on one side of the head with nausea, vomiting, and/or light sensitivity • Head pain (headache) • Cephalgia • Inflammation of the brain • Encephalitis • Water (excess fluid) in the head • Hydrocephalus • Hernia/protrusion of the meninges • Meningocele • Inflammation of the meninges • Meningitis • Inflammation of the spinal cord • Myelitis • Delirium • Acute condition of confusion, agitation, hallucinations (usually caused by high fever)
Stroke • Damage that occurs to the brain when blood flow is disrupted
Brain Injuries • Concussion • the violent shaking up of the brain • Cerebral Contusion • bruising of the brain tissue • Cerebral Hematoma • a collection of blood trapped in the tissues of the brain
Levels of Consciousness • Syncope • Fainting • Lethargy • Lowered level of consciousness (drowsiness, apathy, reduced activity) • Coma • Deep state of unconsciousness • No spontaneous eye movement, speech, or response to pain
Epilepsy • Seizure disorder (recurrent/sudden episodes of surges of electrical activity in the brain)
Brain Disorders • Dementia • progressive decline in mental abilities (memory/thinking/judgment) • Alzheimer’s Disease • progressive deterioration of the brain structures that affect thought/memory/language/reasoning
Brain Disorders (continued) • Parkinson’s Disease • progressive loss of control over muscle movements (tremors, bradykinesia, shuffling gait)
Abnormal Sensations • Burning pain • Causalgia • Condition of excessive sensation (sensitivity to touch/pain) • Hyperesthesia • Abnormal sensation (tingling/prickling) • Paresthesia
Nerve Disorders • Amyotrophic Lateral Sclerosis (ALS) • a/myo/trophic lateral sclerosis • “without muscle development/nourishment” • nerve cells deteriorate and cannot send impulses to the muscles which results in progressive muscle weakness and eventual paralysis • Also called “Lou Gehrig’s Disease”
Nerve Disorders (continued) • GuillainBarre Syndrome • Autoimmune-related inflammation of the myelin sheath of peripheral nerves that can lead to temporary paralysis • Multiple Sclerosis • autoimmune-related demyelination which disrupts the transmission of nerve impulses
Nerve Disorders (continued)Cranial Nerves Bell’s Palsy -temporary paralysis of one of the 7th cranial nerves Trigeminal Neuralgia -lightning-like pain from inflammation of one of the 5th cranial nerves
Nerve Disorders (continued)Spinal Nerves • Sciatica • inflammation of a spinal nerve that results in pain in the thigh/leg
Review & Looking Ahead… • Discussed: Terms related to neurology. • Next class topic: Terms related to mental health. • Quiz 10 Monday, May 12th (A-day) or Tuesday, May 13th (B-day)
