Title: Introduction: Human Anatomy


1
Introduction Human Anatomy Physiology
  • Homeostasis
  • Levels of organization
  • Organization of the body
  • Anatomical terms

De Humani Corporis Fabrica
2
What is A P?
  • Physiology knowledge of nature
  • Aristotle (384-322 B.C.)
  • study of the normal functioning of a living
    organism its component parts
  • Anatomy study of structure

3
Levels of Organization the Related Fields of
Study
4
Integration between systems of the body
5
Homeostasis the ability to maintain a relatively
constant internal environment
6

7
Homeostatic Response Loop
(setpoint)
Local or systemic
8
Feedback Loops Modulate the Response Loop
9
Positive Feedback Loop send variable being
regulated further from its normal value
10
Homeostatic Mechanisms of Body Temperature
11
Concept Check
  • Name in order the sequence of events that occur
    to form a response loop for homeostasis.
  • When we begin to get dehydrated, we usually get
    thirsty, which causes us to drink fluids. Is
    thirst part of a negative or positive feedback
    control system?

12
Organization of the Human Body
  • Axial vs.
    Appendicular
  • cranial cavity upper lower limbs
  • spinal cavity
  • thoracic cavity plural pericardial
  • abdominopelvic cavity
  • Thoracic Abdominopelvic Membranes
  • - Serosa or Serous membranes serous fluid
  • plural membrane
  • pericardial membrane
  • peritoneal membrane

Dorsal body cavity
Ventral body cavity

Body Cavities Lateral view

Body Cavities Anterior View
15
Serous Membranes of the Thorax
16
Peritoneal Membranes of the Abdominopelvic Cavity
17
Anatomical Terminology
  • Relative Positions
  • superior inferior anterior (ventral) posterior
    (dorsal)
  • medial lateral ipsilateral contralateral
  • proximal distal superficial peripheral
  • deep
  • Body Sections
  • sagittal transverse (horizontal) coronal
    (frontal)
  • cross section oblique section
    longitudinal section

Cross Section Oblique Section
Longitudinal Section
21
Terms used to describe anterior body regions
22
Terms used to describe posterior body regions
23
Organ Systems Body Covering
- skin, hair, nails sweat glands sebaceous
glands
24
Support Movement
- bones, ligaments cartilage
- skeletal - cardiac - smooth
25
Integration Coordination
26
Transport
- heart, arteries, capillaries veins
- lymph vessels nodes, thymus spleen
