Flashcards in Ch 26 Vocab Deck (28):
0

Inability to remember events after an injury

Anterograde (posttraumatic) amnesia

1

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)

Basilar skull fractures

2

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

Battles sign

3

Swelling of the brain

Cerebral edema

4

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

Closed head injury

5

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

Concussion

6

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

Connecting nerves

7

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

Coup-contrecoup injury

8

The action of pulling the spine along its length

Distraction

9

An accumulation of blood between the skull and the dura mater

Epidural hematoma

10

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

Eyes-forward position

11

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

Four-person light roll

12

The cushion that lies between two vertebrae

Intervertebral disk

13

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

Intracerebral hematoma

14

The pressure within the cranial vault

Intracranial pressure (ICP)

15

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

Involuntary activities

16

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

Linear skull fractures

17

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

Meninges

18

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

Open head injury

19

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

Primary (direct) injury

20

Bruising under the eyes that may indicate a skull fracture

Raccoon eyes

21

The inability to remember events leading up to a head injury

Retrograde amnesia

22

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

Secondary (indirect) injury

23

Bleeding into the subarachnoid space, where the cerebrospinal fluid circulates

Subarachnoid hemorrhage

24

An accumulation if blood beneath the dura mater but outside the brain

Subdermal hematoma

25

A partial or incomplete dislocation

Subluxation

26

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

Traumatic brain injury (TBI)

27

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

Voluntary activities
