Introduction to Anatomy & Physiology
Headings Vocabulary Important Info
15
Anatomy science of structure relationships revealed by dissection imaging techniques Physiology science of body functions
16
Clinical Observational Techniques
Palpation feel body surface with hands pulses and breathing rates Auscultation listen to body sounds with stethoscope abnormal fluid in lungs Percussion tap on body surface and listen to echo air in intestines
17
Levels of Organization
Chemical Cellular Tissue Organs System Level Organismic Level
18
Levels of Structural Organization
Chemical Level - atomic and molecular level Cellular Level - smallest living unit of the body Tissue Level - group of cells and the materials surrounding them that work together on one task 4 basic tissue epithelium muscle connective tissue nerve
19
Organismic Level - one living individual.
Organ Level grouping of 2 or more tissue types into a recognizable structure with a specific function. Organ System collection of related organs with a common function sometimes an organ is part of more than one system Organismic Level - one living individual.
20
Interactions of Body Systems
Example: Integumentary System & Skeletal System Skin produces vitamin D needed for CA absorption and bone growth Bone marrow produces cells which help the skin resist infection.
21
Life Processes Metabolism = sum of all chemical processes
breakdown of large molecules into small building new structural components (proteins) providing chemical energy for cells Responsiveness detect & respond to changes in internal or external environment some typical responses muscle contraction, electrical signals, hormone or glandular secretion
22
Movement Growth Differentiation Reproduction any structural level
body, organ, cell or cell component Growth increase in number or size of cells or the material found between cells Differentiation specialization of cells for a specific function stem cells give rise to cells that specialize Reproduction formation of new cells or new individuals
23
Autopsy Postmortem examination of body by dissection Purpose
confirm or determine cause of death support findings of other tests provide info on effects of drug usage educate healthcare students reveal congenital defects
24
Homeostatis Maintaining the internal environment within physiological limits (internal balance) First described by French physiologist, Process named by Walter Cannon, Example blood glucose level is kept within narrow range /100ml
25
Homeostasis of Body Fluids
Delineation of fluid compartments Intracellular Fluid (ICF) = w/i cells Extracellular Fluid (ECF) = o/s cells Intercellular Fluid = tissue fluid = interstitial fluid Plasma = fluid portion of blood Composition of fluids change as substances move between compartments nutrients, oxygen, ions and wastes move in both directions across capillary walls
26
Control of Homeostasis
Homeostasis is continually being disrupted by: External Stimuli intense heat, cold , and lack of oxygen Internal Stimuli psychological stresses exercise Disruptions are usually mild & temporary If homeostasis is not maintained, death may result
27
Neural and Endocrine Controls
Maintaining a controlled condition sensory receptors detect change in a monitored variable nervous system and/or endocrine system responds Ex: Control of blood gas level exercise increases blood CO2 levels sensory receptors detect change nervous system increases heart and breathing rates to remove excess CO2 adrenal gland releases epinephrine to increase heart and breathing rates
28
Components of Feedback Loop
Receptor monitors a controlled condition Control Center determines next action Effector receives directions from the control center produces a response that changes controlled condition
29
Negative & Positive Feedback Loops
Negative Feedback Loop original stimulus reversed most feedback systems in the body are negative used for conditions that need frequent adjustment body temperature, blood sugar levels, blood pressure Positive Feedback L loop original stimulus intensified normal childbirth
30
Homeostasis of Blood Pressure
Pressure receptors in walls of certain arteries detect an increase in BP Blood Pressure = force of blood on walls of vessels Brain receives input and signals heart and blood vessels Heart rate slows and arterioles dilate (increase in diameter) BP returns to normal
31
Positive Feedback during Childbirth
Stretch receptors in walls of uterus send signals to brain Brain releases hormone (oxytocin) into bloodstream Uterine smooth muscle contracts more forcefully More stretch, more hormone, more contraction etc. Cycle ends with birth of the baby & decrease in stretch
32
Homeostatic Imbalances
Disorder = abnormality of function Disease = homeostatic imbalance with distinct… Symptoms: changes in body function felt by patient such as nausea Signs: changes in body function that can be observed by doctor such as rash or fever Diagnosis: skill of distinguishing one disease from another Epidemiology: how disease is transmitted Pharmacology: how drugs used to treat disease
33
Basic Anatomical Terminology
Regions of the body Anatomical position Anatomical planes, sections and directional terms
34
Anatomical Position Prone Position = lying face down
Supine Position = lying face up Standardized position describing directional terms standing upright facing the observer, head level eyes facing forward feet flat on the floor arms at the sides palms turned forward
35
Common Regional Names She is standing in the Anatomical Position
Clinical terminology based on a Greek or Latin root word. Fill in worksheet to help remember the terms
36
Planes & Sections Plane: imaginary flat surface that passes through the body. Section: one of the 2 surfaces (pieces) that results when the body is cut by a plane passing through it.
37
Sagittal Plane Sagittal Plane Midsagittal Plane Parasagittal Plane
divides the body or an organ into left and right sides Midsagittal Plane produces equal halves Parasagittal Plane produces unequal halves
38
Other Planes and Sections
Frontal or Coronal Plane divides the body or an organ into front (anterior) and back (posterior) portions Transverse or Horizontal Plane cross-sectional divides the body or an organ into upper (superior) or lower (inferior) portions Oblique Plane some combination of 2 other planes
39

Measure the initial blood pressure and heart rate of two individuals within your group. Next those individuals will walk around the classroom/ hallway at a fast pace for 3minutes. Soon after walking , measure the students blood pressure and heart rate again. In intervals of 30 seconds measure the students heart rate and blood pressure. Finally record the amount of time it took the body to maintain homeostasis. Identify the type of feedback is illustrated in this lab. Make physical observation of the body before walking, after walking, and the cool down.
