1. Journal #1: How might an Anatomist and a Physiologist see a computer differently?
Objectives:
Define Anatomy and Physiology and describe various specialties of each discipline.
Identify the major levels of organism organization from the simplest to most complex
Identify the organ systems of the human body and the major components of each system.
Fun Fact:
For every pound of fat gained you add 7 miles of new blood vessels

2. Chapter 1- An Introduction to Anatomy & Physiology

3. An Introduction to Studying the Human Body
Anatomy- the study of the structures of the body and their relationship to each other
Gross Anatomy- MACROSCOPIC
Surface- or superficial
Regional- focusing on specific areas of the body
Systemic- how organ groups function together
Developmental- focus on changes between conception and maturity also known as embryology
Microscopic Anatomy- Needs Magnification
Cytology- analysis of cells
Histology- examination of tissues

4. An Introduction to Studying the Human Body
Physiology – studies the functions of the human body
Cell- analyzes the chemical processes within and between cells
Special – specialized or focuses on specific organs
Systemic – includes the functioning of entire organ systems
Pathological – studies the effect of diseases on organs and organ systems

5. Levels of Organization
Chemical or Molecular
Cellular
Tissues
Organs
Organ systems
Organism

18. Journal #3: What is a thermostat. How does it work
Journal #3: What is a thermostat? How does it work? What is it’s purpose?
Objective:
Explain Homeostasis and it’s significance for organisms.
Describe how negative and positive feedback are involved in homeostatic regulation.
Fun Fact:
25% of a human’s
bones are in the hands
and feet.

19. Chapter 1- An Introduction to Anatomy & Physiology
Part 2 Homeostasis: * Interactive notes to correspond
with pages 11-14

20. Homeostasis
A condition in which the internal environment of the body(extracellular fluid) remains constant.
Chemical composition
Temperature
Pressure
A failure to maintain homeostasis results in DEATH!!!
How does a jellyfish maintain homeostasis?

21. Homeostatic regulation
The adjustment of physiological systems to maintain homeostasis.
Autoregulation- cell, tissue, organ, or organ system adjust in response to change.
Extrinsic Regulation- nervous or endocrine systems adjust the activities of multiple systems simultaneously.

22. Homeostatic Regulatory Mechanism
Receptor
Senses environmental change
External stimuli
Control Center
Receives & processes stimuli
Sends out command
Effector
Cell or organ that responds to a command

23. Negative Feedback Primary mechanism of homeostatic regulation
A stimulus produces a response that opposes the original stimulus
Example: Control of Body Temperature

25. Positive Feedback Rare
Stimulus creates a response that enhances the original condition rather than opposing it
Can be dangerous or common in stressful conditions

26. Systems Integration, Equilibrium, & Homeostasis
Occurs when opposing processes or forces are in balance
Loss of Homeostasis indicates system abnormality- disease or damage.

27. Journal #3: What are some examples of unavoidable experimental error from yesterdays lab?
Objective:
Explain Homeostasis and it’s significance for organisms.
Describe how negative and positive feedback are involved in homeostatic regulation.
Vocabulary:
10. Effector
11. Negative Feedback
12. Positive Feedback
13. State of Equilibrium

28. Journal #4: What is positive feedback and give an example from the human body?
Objective: (all previously copied)
Explain Homeostasis and it’s significance for organisms.
Describe how negative and positive feedback are involved in homeostatic regulation.
Name the major organ systems & state their function
Fun Fact: 10% of human dry weight comes from bacteria

29. Journal #5: Describe to me how to get to student services from here.
Vocabulary:
14. Anatomical Position
15. Abdominopelvic quadrants
16. Abdominopelvic regions
17. Transverse plane
18. Frontal plane
19. Sagittal plane
Objective:
Use anatomical terms to describe body sections, regions, and positions
Identify the major body cavities and their subdivisions.

30. Chapter 1- An Introduction to Anatomy & Physiology
Part 3 Frames of Reference: * Interactive notes
to correspond with pages 15-22
Anatomy uses a special language to describe
body sections, regions, and relative positions.
Review Figures 1-6, 1-7, 1-8, 1-9, & 1-10

31. Anatomical Position Hands at side, palms facing forward
Standing front = anterior
Standing back = posterior
Laying face up = supine
Laying face down = prone

32. Anatomical Landmarks Based on the structure it is located on or near
Example: Gluteus or buttock region near gluteus muscles

34. Anatomical Regions Clinicians use 4 quadrants
Useful reference for description of pain or injury.
RLQ tenderness is a symptom of Appendicitis
Anatomists us 9 abdominopelvic regions

35. Anatomical Directions

36. Sectional Anatomy 3 planes needed to describe a 3 dimensional object
Transverse - cross section
Frontal- cut in half front & back
Sagittal- cut in half with 2 equal sides

37. Body Cavities (spaces)
Internal chambers with 2 functions:
Protect delicate organs
Allow for change in shape or size of internal organs without disruption of surrounding tissues

38. Membranes Isolate and protect the organs Serous Membranes
Visceral- next to the organ
Parietal- next to the wall of the cavity

39. Ventral Body Cavity (coelom)
Divided by the diaphragm into the
Thoracic cavity
Pericardial cavity - heart
Pleural Cavity - lungs
Abdominopelvic cavity

40. mediastinum divides thoracic cavity into 2 pleural cavities

41. Abdominopelvic Cavity
Peritoneal
Abdominal
Liver
Stomach
Spleen
Intestines
Pelvic
Bladder
Reproductive organs
