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)
