Q

Nervous system functions

A

1) Regulates body activities (nerve impulses)
2) Detects changes in int/ext environment (interprets) ex. step on sharp nail
3) Muscle contraction (voluntary and involuntary muscles) and glandular secretions (works hand in hand with the endocrine system to maintain homeostasis in the body)
4) Most important system for sustaining life

25
Digestive System Functions
- Achieves physical (physical mastication) and chemical breakdown (saliva, stomach acid) of food - Absorbs nutrients (distributes to where needed in the body) - Eliminates solid wastes
26
Respiratory System Components
Lungs and Series of associated passageways (pharynx, larynx, trachea)
27
Respiratory System Functions
- Transfer O2 (Oxygen) from inhaled air to blood - Transfer CO2 (Carbon Dioxid) from blood to exhaled air - Regulates acid- base balanced of body fluids (regulate homeostasis) - Air flowing out of lungs through vocal cords produces sounds
28
What is Cardiovascular System often referred as?
The "circulatory" system
29
Cardiovascular System Components
Blood, Heart, and blood vessels
30
Cardiovascular System Functions
- Blood carries O2 and nutrients to cells - Carries CO2 and wastes from cells - Regulates acid—base balance, temperature, & H2O content of body fluids (maintain homeostasis) - Help defend against disease and mend damaged blood vessels WORKS HAND IN HAND WITH LYMPHATIC
31
Lymphatic System Components
Lymphatic fluid/vessels, spleen, tonsils, etc
32
Lymphatic System Functions
- Returns proteins and plasma to CV system - Carries lipids from GI tract to blood - Protect against disease-causing microbes (bacteria, viruses)
33
Integumentary System Components
Skin and structures derived from it such as: | hair, nails, sweat and oil glands
34
Integumentary System Function
- Protects the body (skin is the bodies largest organ) - Helps regulate body temperature (maintain homeostasis) - Eliminates some waste (ex. sweating) - Detects sensations such as touch, pain, warmth, and cold
35
Anatomical Terminology
Language of Anatomy
36
What does the Anatomical Position look like?
- Standing Upright - Arms at sides, Palms facing forward - Head facing forward - Feet flat on floor, facing forward
37
What is it called when the body is laying face down?
Prone
38
What is it called when the body is facing up?
Supine
39
Regional names (6)
- Head: Skull and Face - Neck: Supports the head and attaches it to trunk - Trunk: Chest, abdomen, and pelvis - Upper Limbs/extremity: shoulder, armpit, arm, forearm, wrist, hand, and finger - Lower Limbs/extremity: buttock, thigh, leg, ankle, foot, and toes
40
Directional Terms
- Used by anatomists to locate structures - Words that describe the position of one body part relative to another - Mostly grouped into pairs
41
Superior vs. Inferior (Directional terms)
Superior (cranial or cephalic) towards the head or upper part of structure Inferior (caudal) Away from head or lower part of structure
42
Anterior vs. Posterior (Directional terms)
Anterior (ventral or belly side) nearer to front of body Posterior (dorsal or back) nearer to back of the body
43
Medial vs. Lateral (Directional Terms)
Medial - Nearer to the midline Lateral - Farther from the midline

Proximal - Nearer to point of attachment of a limb to the trunk; nearer to origination of a structure Distal - Farther from point of attachment of a limb to the trunk; farther from origination of a structure
45
Superficial vs. Deep (Directional Terms)
Superficial - Towards or on surface of body Deep - Away from surface of body
46
Internal vs. External (Directional Terms)

1) Pericardial cavity 2) Pleural cavities (2) 3) Mediastinum
57
Pericardial Cavity (compartment of thoracic cavity)
fluid-filled space that surrounds the heart
58
Pleural cavities (2)(compartment of thoracic cavity)
Each pleural cavity surrounds one lung and contains a small amount of fluid
59
Mediastinum (compartment of thoracic cavity)
Region between the lungs, extending from the sternum to the V.C. and from neck to the diaphragm Contains all the thoracic organs except the lungs themselves Heart, esophagus, trachea, thymus, and several large blood vessels
60
Abdominopelvic Cavity
