Define
- anatomical position - body is ERECT with FEET only slightly apart, head and toes pointed FORWARD, and arms HANGING AT SIDES with PALMS facing forward
- axial region - includes HEAD, NECK, and TRUNK, it runs along VERTICAL axis of the body
- appendicular region - includes the LIMBS, which are also called appendages or EXTREMITIES
- superior/inferior - ABOVE/BELOW
- anterior/posterior - FRONT/BACK
- medial/lateral - TOWARD THE MIDLINE/AWAY FROM THE MIDLINE
- cephalad (cranial)/caudal - TOWARD THE HEAD/TOWARD THE TAIL
- ventral/dorsal - BELLY SIDE/BACKSIDE
- proximal/distal - NEAR ATTACHED END/AWAY FROM POINT OF ATTACHMENT
- superficial (external)/deep (internal) - TOWARD OR AT BODY SURFACE/AWAY FROM BODY SURFACE
- section - CUT
- plane - SECTION MADE ALONG AN IMAGINARY SURFACE OR LINE
- midsagittal plane/median - PLANE DIVING BODY INTO EQUAL LEFT AND RIGHT PARTS
- frontal/coronal plane - DIVIDES BODY INTO ANTERIOR AND POSTERIOR PARTS

Name ALL the phases of mitosis
- Interphase
- Early prophase
- Late prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
*
What are the 3 distinct periods of interphase? What happens during interphase?
What are the 3 distinct periods of interphase?
- G1 - centrioles begin replicating
- S - DNA is replicated
- G2 - Final preparations for mitosis are completed and centrioles finish replicating
What happens during interphase?
cell carries out normal metabolic activities and grows
What happens during early prophase? Late prophase?
What happens during early prophase?
- chromatin condenses
What happens during late prophase?
- nuclear envelope breaks up (spindles interact with chromosomes)
What happens during metaphase? Anaphase?
What happens during metaphase?
- chromosomes line up at the midline of cell
What happens during Anaphase? (Shortest phase of mitosis)
- daughter chromosomes move to opposite sides of cell
What happens during telophase? Cytokinesis?
What happens during telophase?
- nuclear envelope forms around each chromatin, nucleoli reappear, spindle breaks down and disappears
Cytokinesis? (Begins in late anaphase and continues beyond telophase)
- contractile ring of actin microfilaments forms cleavage furrow and pinches cell apart
Explain
- diffusion -
- osmosis -
- filtration -
Explain
- diffusion - MOVEMENT OF MOLECULES FROM A REGION OF HIGH TO LOW CONCENTRATION
- osmosis - FLOW OF WATER ACROSS A SELECTIVELY PERMEABLE MEMBRANE (DOWN CONCENTRATION GRADIENT)
- filtration - WATER AND SOLUTES ARE FORCED THROUGH A MEMBRANE BY HYDROSTATIC (FLUID) PRESSURE
What is the percentage of physiological saline?
What is the percentage of physiological saline?
0.9%
Define
- hypertonic
- hypotonic
- isotonic
- lysis
- crenation
Define
- hypertonic - SOLUTION HAS HIGHER SOLUTE CONCENTRATION THAN CELL, WATER MOVES OUT THE CELL AND INTO SOLUTION
- hypotonic - SOLUTION HAS LOWER SOLUTE CONCENTRATION THAN CELL, WATER MOVES INTO THE CELL CAUSING IT TO EXPAND IN SIZE
- isotonic - CONCENTRATION OF SOLUTE IS THE SAME INSIDE AND OUTSIDE OF CELL, WATER MOVES ACROSS MEMBRANE IN BOTH DIRECTION MAINTAINING CELL SIZE
- lysis - CELL FILLS UP, EXPANDS, AND EXPLODES
- crenation - SHRINKAGE OF CELLS
General characteristics of the following tissues
- muscular
- epithelial
- nervous
- connective
General characteristics of the following tissues
- muscular - CONTRACTION, PRODUCE BODY MOVEMENTS
- epithelial - SHEET OF CELLS THAT COVERS BODY SURFACE/LINES BODY CAVITY, PROTECTION, ABSORPTION, FILTRATION, EXCRETION, SECRETION, AND SENSORY RECEPTION
- nervous - NEUROGLIA SUPPORT CELLS THAT PROTECT, SUPPORT, AND INSULATE MORE DELICATE NEURONS, NUERONS RECIEVE STIMULI (EXCITABILITY) AND GNERATE ELECTRICAL SIGNALS TO SEND ALL OVER BODY (CONDUCTIVITY)
- connective - FOUND ALL OVER BODY, MOST ABUNDANT, PROTECT, SUPPORT, INSULATE, AND BIND TOGETHER OTHER TISSUES OF BODY
