Q

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)

A

Basilar skull fractures

1
Q

Inability to remember events after an injury

A

Anterograde (posttraumatic) amnesia

2
Q

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

A

Battles sign

3
Q

Swelling of the brain

A

Cerebral edema

4
Q

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

A

Closed head injury

5
Q

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

A

Concussion

6
Q

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

A

Connecting nerves

7
Q

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

A

Coup-contrecoup injury

8
Q

The action of pulling the spine along its length

A

Distraction

9
Q

An accumulation of blood between the skull and the dura mater

A

Epidural hematoma

10
Q

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

A

Eyes-forward position

11
Q

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

A

Four-person light roll

12
Q

The cushion that lies between two vertebrae

A

Intervertebral disk

13
Q

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

A

Intracerebral hematoma

14
Q

The pressure within the cranial vault

A

Intracranial pressure (ICP)

15
Q

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

A

Involuntary activities

16
Q

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

A

Linear skull fractures

17
Q

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

A

Meninges

18
Q

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

A

Open head injury

19
Q

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

A

Primary (direct) injury

20
Q

Bruising under the eyes that may indicate a skull fracture

A

Raccoon eyes

21
Q

The inability to remember events leading up to a head injury

A

Retrograde amnesia

22
Q

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

A

Secondary (indirect) injury

23
Q

Bleeding into the subarachnoid space, where the cerebrospinal fluid circulates

A

Subarachnoid hemorrhage

24
Q

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

A

Subdermal hematoma

25
Q

A partial or incomplete dislocation

A

Subluxation

26
Q

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

A

Traumatic brain injury (TBI)

27
Q

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

A

Voluntary activities
