Trauma and Injury to the Nervous System - Chapter Summary and Objectives

Pathology, which combines the scientific fields of pathology and physiology, examines functional changes to the human body that are caused by diseases or disorders. This chapter on trauma and injury to the nervous system explores how the nervous system works and how certain injuries and illnesses can affect its functions. Through this series of video lessons, you can learn to do the following:

  • Differentiate between motor and sensory neurons.
  • Specifically identify where epidural hematoma can occur.
  • Explain the role of receptors and hormones in how your body reacts to pain.
  • Discuss the phases of spinal shock.
  • Identify various treatments for stroke, including thrombolysis and neurosurgery.

VideoObjective
Functions of the Nervous SystemLearn about sensory organs and the three functions of the nervous system.
The Structure and Function of NeuronsExplore neuron anatomy and learn about membrane polarization and depolarization.
Pain: Types, Mechanisms and TreatmentDiscuss different types of pain and ways it can be assessed. Explore the role of receptors and hormones as well as treatment options.
Dangerous Injuries to the HeadExamine blunt trauma, increased intracranial pressure, hematomas and craniofacial trauma. Learn how craniofacial trauma can result in leakage of cerebrospinal fluid from the body.
Epidural Hematoma: What it is and Where it OccursExplore the causes of epidural hematoma and where it occurs.
The Mechanism of Spinal Cord TraumaLearn about spinal shock and autonomic dysreflexia.
Vascular Abnormalities of the Nervous SystemDiscuss causes, symptoms and pathology of transient ischemic attacks (TIA) and strokes. Learn about possible treatments, including anticoagulants.

Functions of the Nervous System

1. Functions of the Nervous System

In this lesson, we'll watch Timmy as he plays in his backyard. Watch what happens when he tries to catch a butterfly, hears a mean dog bark, and scrapes his knee. All of Timmy's reactions are tied to his nervous system. For a full explanation of what goes on in the human nervous system, check out the video!

The Structure and Function of Neurons

2. The Structure and Function of Neurons

In this video lesson, you'll learn about neurons, which are specialized cells in the nervous system. Check out how far neurons can send signals throughout the body and how depolarization is much like 'the wave' at a football game.

Pain: Types, Mechanisms, and Treatment

3. Pain: Types, Mechanisms, and Treatment

This lesson will cover the basics of pain. We'll discuss the different types of pain, the basic mechanism of pain, what structures are involved, and how your own body or drugs try to stop it.

Dangerous Injuries to the Head

4. Dangerous Injuries to the Head

This lesson will underscore the different types of traumas that can occur to your head. We will go over blunt, penetrating, perforating, and craniofacial trauma, as well as some of their unique components.

Epidural Hematoma: What it is and Where it Occurs

5. Epidural Hematoma: What it is and Where it Occurs

We'll go over something known as an epidural hematoma. This lesson will explain what it is, what may predispose an individual to get one, and how it is best avoided. We'll also explore the signs and symptoms, diagnostics, and treatments involved in this event.

The Mechanism of Spinal Cord Trauma

6. The Mechanism of Spinal Cord Trauma

This lesson will go over the things that can traumatize your spinal cord, what spinal cord trauma may result in, and why that may occur. We'll also focus in on some of the specifics of spinal shock and autonomic dysreflexia.

Epilepsy: Causes, Types, and Treatments

7. Epilepsy: Causes, Types, and Treatments

This lesson will go over seizures and epilepsy. We'll define the difference, go over why it may occur, how it is diagnosed, and how some treatments work to stop the seizures that cause epilepsy.

Vascular Abnormalities of the Nervous System

8. Vascular Abnormalities of the Nervous System

This lesson will discuss a lot of different yet similar conditions that affect the brain's vasculature. Namely, we'll cover strokes, transient ischemic attacks, and aneurysms. We'll also discuss why they may occur, how they can be diagnosed, and how they may be treated.
