1

Nervous system: Brain injury (BI)

Traumatic brain injury

An insult to the brain caused by external physical force that may result in finished or altered state of consciousness.

2

Nervous system: brain injury (BI)

Acquired brain injury

Does not result for traumatic history to the head, is not hereditary, congenital, or degenerative, and occurs after birth. Included in this category are oxygen deprivation, aneurysms, infections to the brain, and stroke.

3

Nervous system

Provides the structure and process for communicating sensory perceptual and automatically generated information throughout the body.

4

Nervous system: subsystem

Central nervous system

The brain and spinal cord

5

Nervous system: subsystem

Peripheral nervous system

Spinal and cranial nerves

6

Nervous system: subsystem

Automatic nervous system

Nerves controlling cardiovascular, gastrointestinal, genitourinary, and respiratory systems.

7

Neuron

Basic working unit of all the nervous systems and has a diversity of neuronal types.

8

Axon

Cell body with nucleus and conduction fiber.

9

Synapse

Connection between axon and dendrite.

Is the gap between the two.

10

Neurotransmitters

The chemical and electrical ways synapses communicate.

11

Neurotransmitter:

Acetylcholine

Active neurotransmitter in central and peripheral nervous system.

Critical for memory.

12

Dopamine

Plays a role in influencing emotional behavior, cognition, and motor activity.

13

Norepinephrine

Appears throughout the body and plays a role in memory and learning.

Connects brain stem to cerebral cortex.

14

Serotonin

This neurotransmitter is thought to play a role in sensory process, muscular activity, thinking, state of consciousness, mood, depression diagnosis, and anxiety diagnosis.

Lines digestive tract and in tract from the midbrain to all brain regions.

15

Frontal lobe function

Motor behavior
Expressive language
Social functioning
Concentration and ability to attend
Reasoning and thinking
Orientation to time, place, and person.

16

Temporal lobe function

Language
Memory
Emotions

17

Parietal lobe function

Intellectual processing
Integration of sensory information
-left side: verbal processing
-right side: visual/spatial processing

18

Occipital lobe function

Vision

19

Amino acids

Plays a critical role in inhibiting the firing of impulses of functioning of central nervous system.

Helps with locomotor activity, cardiovascular reactions.

20

Peptides

Play a role in activities such as moderating pain and causing sleepiness.

Opioids are a type of peptides.

21

Endocrine system

Plays a crucial role in our growth, metabolism, development, learning, and memory.

Made up of glands that secrete hormones into the blood system.

22

Diabetes mellitus

Most common illness caused my hormonal imbalance.

23

HIV

Human immunodeficiency virus

1/250 infected

Leads to AIDS

24

AIDS

acquired immunodeficiency syndrome.

25

Immune system

Made up or organs and cells that work together to defend the body against disease.

26

Antigens

Foreign substance that can trigger an immune response.

Includes bacteria, fungi, viruses.

27

Autoimmune disease

When the immune system is mistaking my directed at parts of the body it was designed to protect.

28

Lymphocytes

White blood cells.

Developed by organs in the immune system.

29

Non-specific immunity

Cells and phagocytes circulate in the blood and lymph and ingest antigens at the site of the wound.

30

Specific immunity

Lymphocytes respond to an infection by developing a memory of infection that allows the body to make rapid defense against it.
