Body Wall(Skin)
Contains brain and organ of sight
Head Region(Skull)
8 distinct bones of human skull that eventually fuse together to house and protect the brain
Cranium
14 bones from head to chin, from ear to ear not including ears
Face
Lower constricted portion of body inferior to head
Neck Region(Cervical)
Portion not including head, neck, upper and lower extremities
Trunk Region(Torso)
Portion located above diaphragm, upper dome shape muscle
Thorax(Thoracic)
Located inferior, below, beneath diaphragm
Abdomen(Abdominal Region)
Located within bones of pelvic region
Pelvis(Pelvic Region)
Arm appendages
Upper Extremities
Leg appendages
Lower Extremities
Spaces naturally present in body that house organs
Body Cavities
Space inside 8 cranial bones, -organ - brain only
Cranial Cavity(Skull cap/Cavertium)
Space inside spine or bones of vertebra column -Organ - spinal cord
Spinal Cavity(Canal)
Space located above diaphragm -organs - lungs heart, trachea “windpipe”, esophagus, large blood vessels [aorta, superior vena cava/2nd largest vein/drain blood from upper extremities]
Thoracic Cavity
Space located inferior/beneath diaphragm (organs - liver, gallbladder, stomach, pancreas, spleen, small intestine, appendix, large intestine/water removal, kidneys/chief organ of urine system, urinary bladder/protected by pelvic bone, prostrate, uterus, ovaries)
Abdominal - Pelvic Cavity
2 or more organs combining together to form common function (highest level of organization)
System
Study of skin and accessory structures (hair, nails)
Integumentary System
Study of bones of the body
Skeletal System
Study of organs involved in breaking down food and liquids we ingest into useable soluble substance
Digestive System
Study of organs involved in breathing, 2 steps inhale & exhale (most important-rid waste), exchange of oxygen from outside air for waste gases called carbon dioxide
Respiratory System
Study of ductless glands-gland: any organ that release useful substances called secretion
Endocrine System
Study of organs producing or wasting secretions/waste products (urinary system most important waste secretion)
Excretory System
Study of organs that produce and transmit nerve sensors throughout the body-central nervous system (CNS), brain & spinal column-peripheral nervous system (PNS), send signal from base to spinal nerves to brain
Nervous System
Study of organs of production of offsprings
Reproductive System
Muscles of the body, organs involved in the movement of and within the body
Muscular System
Production and shipment of blood throughout the body; key to embalming process
Circulatory System
2 or more tissues combined together to perform common function (IE: liver, stomach, & spleen work together for digestion. Liver “largest single organ inside your body.
Organ
2 or more cells combined together to perform common function (ligaments/tendons, cartilage/bone/fat)
Tissue
Lining tissue, outer layer of body, innermost layer of any -organ - blood vessels, GI track
Epithelia Tissue
Connects or joints parts of the body to each other -ligaments-connects bone to bone; -tendons-connects muscle to bones; -cartilage-within our rib cage; -bones-hardest connective tissue; -fat
Connective Tissue
Movement of & within the body -cardiac-heart/100% involuntary muscle-skeletal-attached indirectly to bone-visceral-organ tissues made of smooth tissues
Muscle Tissue3 Types: Cardiac, Skeletal, Visceral
Transmit nerve impulses-neuron/nerve cell
Nervous Tissue
Structural and functional units of life-lowest level of organization in the human body
Cells
An imaginary line drawn on the surface of the skin to represent the approximate location of some deeper lying structure
Linear Guide
Method of locating structure by reference to an adjacent known or prominent structure
