Emt Chapter 26

Front 1

Anterograde (Post-Traumatic) Amnesia

Back 1

Inability to remember events after an injury.

Front 2

Basilar Skull Fracture

Back 2

Usually occur following diffuse impact to the head (such as falls, motor vehicle crashes); generally result from extension of a linear fracture to the base of the skull and can be difficult to diagnose with a radiograph (x-ray).

Front 3

Battle's Sign

Back 3

Bruising behind an ear over the mastoid process that may indicate a skull fracture.

Front 4

Cerebral Edema

Back 4

Swelling of the brain.

Front 5

Closed Head Injury

Back 5

Injury in which the brain has been injured but the skin has not been broken and there is no obvious bleeding.

Front 6

Concussion

Back 6

A temporary loss or alteration of part or all of the brain's abilities to function without actual physical damage to the brain.

Front 7

Connecting Nerves

Back 7

Nerves in the spinal cord that connect the motor and sensory nerves.

Front 8

Coup-Contrecoup Injury

Back 8

Dual impacting of the brain into the skull; coup injury occurs at the point of impact; contrecoup injury occurs on the opposite side of impact, as the brain rebounds.

Front 9

Distraction

Back 9

The action of pulling the spine along its length.

Front 10

Epidural Hematoma

Back 10

An accumulation of blood between the skull and the dura mater.

Front 11

Eyes Forward Position

Back 11

A head position in which the patient's eyes are looking straight ahead and the head and torso are in line.

Front 12

Four-Person Log Roll

Back 12

The recommended procedure for moving a patient with a suspected spinal injury from the ground to a long backboard.

Front 13

Intervertebral Disk

Back 13

The cushion that lies between two vertebrae.

Front 14

Intracerebral Hematoma

Back 14

Bleeding within the brain tissue (parenchyma) itself; also referred to as an intraparenchymal hematoma.

Front 15

Intracranial Pressure (ICP)

Back 15

The pressure within the cranial vault.

Front 16

Involuntary Activities

Back 16

Actions of the body that are not under a person's conscious control.

Front 17

Linear Skull Fracture

Back 17

Account for 80% of skull fractures; also referred to as nondisplaced skull fractures; commonly occur in the temporal-parietal region of the skull; not associated with deformities to the skull.

Front 18

Meninges

Back 18

Three distinct layers of tissue that surround and protect the brain and the spinal cord within the skull and the spinal canal.

Front 19

Open Head Injury

Back 19

Injury to the head often caused by a penetrating object in which there may be bleeding and exposed brain tissue.

Front 20

Primary (Direct) Injury

Back 20

An injury to the brain and its associated structures that is a direct result of impact to the head.

Front 21

Raccoon Eyes

Back 21

Bruising under the eyes that may indicate a skull fracture.

Front 22

Retrograde Amnesia

Back 22

The inability to remember events leading up to a head injury.

Front 23

Secondary (Indirect) Injury

Back 23

The "after effects" of the primary injury; includes abnormal processes such as cerebral edema, increased intracranial pressure, cerebral ischemia and hypoxia, and infection; onset is often delayed following the primary brain injury.

Front 24

Subarachnoid Hemorrhage

Back 24

Bleeding into the subarachnoid space, where the cerebrospinal fluid circulates.

Front 25

Subdural Hematoma

Back 25

An accumulation of blood beneath the dura mater but outside the brain.

Front 26

Subluxation

Back 26

A partial or incomplete dislocation.

Front 27

Traumatic Brain Injury (TBI)

Back 27

A traumatic insult to the brain capable of producing physical, intellectual, emotional, social, and vocational changes.

Front 28

Voluntary Activites

Back 28

Actions that we consciously perform, in which sensory input or conscious thought determines a specific muscular activity.
