Ch. 10 The Nervous System

Medical Terminology

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)

Structures

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

Cranial Nerves

Spinal Nerves

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

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.

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

Alzheimer’s- Under the Microscope

Alzheimer’s- Brain Comparison

Alzheimer’s- The Progression

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)

Guillain Barre 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

Video: Traumatic Brain Injury (TBI)
