Define Inferior (position)
Situated below or lower than another part
Define Central
Near the center of the body or middle of an organ
Define Peripheral
Away from the center of the body
What are the three anatomic planes?
1. Frontal Plane: divides the body inot a front (anterior) portion adn a rear (posterior) portion
2. Sagittal Plane: vertical divides the body lenthwise into right and left sections
Midsagittal: down middle
Longitudinal: any point
3. Transverse plane: divides body horizontally into top (superior) and bottom (inferior) portions (can go anywhere: cross sections)
What are the two major portions of the body?
1. Axial
2. Appendicular: limbs

Body cavities are holes where organs are held. What are the two main body cavities and what cavities do they house?
1. Dorsal Cavity
a. Cranial cavity: brain
b. spinal cavity: spinal cord
2. Ventral Cavity (divided by the diaphram)
a. thoracic cavity: heart and lungs
b. abdomino-pelvic: stomach, liver, gall-bladder, spleen, most intestines; reproductive organs, bladder, rectum and lower portion of the intestines
The abdomen is divided into quadrants and regions. Name these
1. Right Upper
2. Left Upper
3. Left Lower
4. Right Lower
1. Epigastric: above the stomach and in the central part of the abdomen just above the naval
2. Hypochondriac: lies to the right and left of the epigastric region and just below the cartilage of the rib cage
3. Hypogastric: Below the stomach and in the central part of the abdomen just below the navel
4. Iliac: lies to the right and left fo the hypogastric regions near the hip bones
5. Umbilical: the area aroudn the navel
6. Lumbar: Froms the region of the lower back to the right and left fo the umbilical region
What is a pathogen
an agent that causes disease
(2 types of reactions that occur?)
describes all the chemical reactions that occur in the body

Anabolic: create needed products

Catabolic: break down products
What is the form of energy used by cells?
ATP (Adenosine triphosphate)
What processes are involved in cellular respiration which converts energy from fuel into ATP?
1. Glycolosis
2. Aerobic (Kreb's cycle) & Anaerobic respiration
3. Oxidative Phosphorylation
How is the nervous system divided?
CNS: Central Nervous System; includes the brain a spinal cord

PNS: Peripheral nervous system; consists of the nerves that project out from the brain and spinal cord
What is the definition of a nerve? and what two types of nerve fibers are there?
a nerve is a vessel that contains nerve fibers and connects them to the CNS

Motor: send impulses away from the CNS

Sensory: Send impuses toward the CNS
What does the PNS consist of in terms of nerves and fibers?
Cranial Nerves: stem from the brain

Spinal Nerves: stem from the spinal cord

Sensory fibers: are all over the body and send impulses to the CNS via the cranial and spinal nerves

Motor fibers: Which connect to muscles and glands and send impulses from the CNS via the cranial and spinal nerves.
The PNS is divided into two systems. What are these and how does each function?
The Somatic System: consists of motor fibers sending impulses FROM the CNS to the voluntary skeletal muscles, as well as sensory fibers receiving input from receptors in the skin and initiating impulses as a reaction to the input

The Autonomic system: consists of motor fibers sending impulses FROM the CNS to the glands, the heart and involuntary smooth muscle (as in organs) and is made up of:
The Sympathetic nervous system: Nerves originate in the thoracic and lumbar regions of the spinal cord

The parasympathetic nervous system: nerves originate in the brain and sacrum

~They both control internal organ functions that are involuntary and that happen subconsciously, such as breathing, heartbeat, and digestion
