Brain vs Computer
• Both tremendous capacity to
store
information • Computer can easily retrieve information due to software designed to organize information storage that allows for fast and easy retrieval.
• Our brains have same capacity but we have to “program” the brain to retrieve • “Basket of socks” analogy - connections create organization
Chapter 1 Introduction to Human Anatomy and Physiology
• Expanding your knowledge base!
“jungle gym analogy” 1. Comprehension – ability to read or hear → understand 2. Study skills – reading rate, memorization aptitude, “brain hooks - socks” 3. Discipline –
preview chapters
, studying material on daily basis outside of class 4. Organization – notes, flash cards, lists, drawings, reviews 5. Prior knowledge base – previous courses in college or high school 6. Hard work – hours put in if not proficient in basics – plan now!
7. Correlate material – acronyms, analogies, personalize 8. Study partners or groups – 2 or more viewpoints clears understanding 1-2
How To Achieve Your Grade!
1. Lecture tests make up 70% of grade!
2. Attend classes – penalty if over 4 misses 3. Do chapter summaries 4. Do chapter review exercises (bonus) 5. Turn in all articles – 10 in 12 weeks 6. Pass all open book/notes quizzes (>70%) – are pass or fail 7. Give blood and do community service project 8. Study bonus questions given out before tests – 8 to 10 given for each test but only 2 on each lab or lecture test 9. Participate in class
Anatomy and Physiology
Anatomy – study of structure Physiology – study of function Structure is always related to function

Levels of Organization
1-5
Levels of Organization
Atom
“Building blocks of the organism”
– hydrogen, carbon, nitrogen, oxygen atoms Molecule – water , glucose, NaCl molecules Macromolecule Organelle – protein molecule, DNA molecule – mitochondria, Golgi apparatus, ribosome, lysosome, cell membrane, nucleus Cell – muscle cell, nerve cell, bone cell- ( 70 trillion ) Tissue – bone tissue, muscle tissue, nerve tissue Organ – skin, femur, heart, kidney, liver Organ System – skeletal system, digestive system, integumentary system, circulatory system Organism – human, cat, dog

Characteristics of Life - 10
1) Movement – change in position; motion – inside and outside 2) Responsiveness – reaction to a change 3) Growth – increase in size 4) Reproduction – production of new organisms and new cells 5) Respiration – obtaining oxygen; removing carbon dioxide; releasing energy from foods
1-6
Characteristics of Life
6) Digestion – breakdown of food substances 7) Absorption – passage of substances through membranes and into body fluids 8) Circulation – movement of substances in body fluids 9) Assimilation – changing of absorbed substances into different substances 10) Excretion – removal of wastes
1-7
Metabolism
• Physical and chemical events that release and utilize energy • All the previous characteristics of life involve metabolism
Table 1.4, p. 9
Requirements of Organisms
Water most abundant substance in body - required for metabolic processes - required for transport - regulates body temperature Food - supply energy - supply raw materials
1-8
Requirements of Organisms
Oxygen - one-fifth of air - used to release energy from nutrients Heat form of energy - partly controls rate of metabolic reactions Pressure - atmospheric pressure (exerted by gas) – important for breathing hydrostatic pressure (exerted by fluids) – keeps blood flowing
1-9
Homeostasis
“Body’s maintenance of a stable internal environment” Homeostatic Mechanisms – monitor aspects of the internal environment and corrects any changes
•
Receptors - provides information about internal and external environment
•
Control center - tells what a particular value should be and processes a response to information
•
Effectors - causes response to change of internal environment
•
Positive feed back – promote frequency & intensity of process – ie ↑ breathing rate with exercise
•
Negative feedback – reverses trend of process – ie rising internal body temperature above 98.6 F
Homeostatic Mechanisms
1-11
Body Cavities
Thoracic cavity = pleural cavity (lungs) + mediastinum (heart, esophagus, thymus, trachea) ↓ Diaphram ↓ Abdominopelvic cavity = abdominal cavity (stomach, pancreas, liver, spleen, gallbladder, large and small intestine + pelvic cavity (terminal large intestine, urinary bladder, reproductive organs) 1-12
Serous Membranes
Visceral layer Parietal layer – covers an organ – lines a cavity or body wall-”guards perimeter” Thoracic Membranes Visceral pleura ( lungs ) Parietal pleura ( lungs ) Visceral pericardium ( heart ) Parietal pericardium ( heart ) Abdominopelvic Membranes
•
Visceral peritoneum
•
Parietal peritoneum

Anatomical Terminology
Anatomical Position – body standing erect, facing forward, upper limbs at the sides, palms facing forward Terms of Relative Position
•
Superior versus Inferior – top vs bottom
•
Anterior versus Posterior –
•
Medial versus Lateral – front vs back of structure middle vs away from middle of structure
•
Ipsilateral versus Contralateral –
•
Proximal versus Distal – same side vs opposite side closer to body vs away from body – usually associated with extremities
•
Superficial versus Deep –
↓ •
Peripheral – near surface vs more internal outward from central structure or near surface
1-18
Body Sections
•
Sagittal / Median leave left & right portions
•
Transverse / Cross - leave top & bottom portions
•
Coronal or Frontal - leave front & back portions
•
Oblique cut at angle in any of the planes

Abdominal Subdivisions
Vertical line – through center of breast Horizontal line – 11 th rib & ASIS of pelvis “Cross hairs” on navel Locate: liver, gall bladder, stomach, pancreas, large intestine, small intestine, spleen, diaphram, urinary bladder
