body cavities
cranial cavityvertebral canal thoracic cavityabdominopelvic cavity
endocrine system
abdominopelvic cavity, pelvic cavity all glands, ovaries, testessecrete hormones, chemical messengers
lymphatic system
lymph nodes, spleen, thymus, transport waste, protect from infection, remove pathogens
urinary system
kidneys, bladder, urethraremove waste, maintain water / electrolyte balance
DT: superior
part is above another part
DT: inferior
part is below another part
DT: anterior
part is towards front
DT: posterior
part is towards the back
DT: medial
closer to midline (middle) of body, than another part
DT: lateral
toward side, away from midline
DT: bilateral
paired structures (one on each side)
DT: ipsilateral
structures on the same side
DT: contralateral
structures on opposite side
DT: proximal
part closer to point of attachment at trunk of body(elbow is proximal to wrist)
DT: distal
part is further from point of attachment at trunk of body(wrist is distal to elbow)
DT: superficial
near surface
DT: deep
describes internal parts
DT: transverse
divides body into superior/inferior portions (top/bottom)
DT: sagittal
lengthwise cut dividing body left and right, facing forwardif cut follow midline = median sagittal
DT: frontal
divides body anterior/posterior (front back), from side view

3 major parts of cell
NucleusCytoplasm (water like fluid)Cell membrane (balloon filled with water)
Cell membrane
maintains integrity of the cellpermeable, lets substances in/out proteins act as gatekeeper
Cytoplasm
cytosil (liquid) + organelles
Cyto-organelle: Ribosomes
protein synthesisRER (rough endoplasmic reticulum)
Cyto-organelle: Endoplasmic Reticulum
RER= protein synthesisSER (smooth)= fat synthesistransport area
Cyto-organelle: Vesicles
balloon-like sacs transport/store material in and out of cell
Cyto-organelle: Golgi Apparatus
packages proteins for transport
Cyto-organelle: Mitochodria
powerhousefound in areas of high activity
Cyto-organelle: Lysosomes
garbage collectors contains enzymes that process waste
Cyto-organelle: Centrosomes
involved in cell devision produce spindle fibers during mitosis
Nucleus
tells cells when to divide / what to manufacture.
4 Cell Movement Passive Physical
DiffusionFacilitated DiffusionOsmosisFiltration
Diffusion
Molecules move from high concentration area to low concentration area
Facilitated Diffusion
Ions move through channels, molecules move by carrier proteins from high concentration to low concentration
Osmosis
moves water through permeable membranecreates pressure on one side of membrane
Filtration
smaller molecules forced through membrane
Cell cycle
Interphase = genetic material replicatesMitosis = division of nucleusCytokinesis = division of cytoplasm
Mitosis: Interphase
Synthesizes DNA and materials for organelles
Mitosis: Prophase
Chomatin fibers condense Centrioles move to opposite poles Loss of nuclear membrane
Mitosis: Metaphase
Chromosomes align in centerCentrioles at opposite ends, attach to chromatin
Mitosis: Anaphase
Chromosomes pulled apart towards opposite poles of cell
Mitosis: Telophase
Chromosomes reach opposite poles/centriolesReverse-prophase: nucelic membrane reforms
