What are the 4 main topics of anatomy
- Gross anatomy
- Surface anatomy

- Developmental anatomy
Gross anatomy
Study of structures visible to the eye
Regional anatomy
Study of structure in a specific region (thoracic; chest)
Systemic anatomy
Study of structure of a system
Surface anatomy
Study of surface structure
Microscopic anatomy
Study of structures too small to see with the naked eye. (Needs a microscope)
Cytology

Histology
Study of tissues
Developmental anatomy
Study of change in anatomy throughout the lifespan
Embryology
Study of developmental prior to birth
Compare and contrast anatomy and physiology
Form = function
What are the topics of physiology and how are topics in physiology discussed?
Focus on a specific organ or system.
Renal, cardiovascular, and neurophysiology
What are the 4 main underlying themes in physiology?
- Structure and function are closely related.
- Living organisms need energy
- Information flow coordinates body functions
- Homeostasis maintains internal stability
What are the main properties of life?
Maintain boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and growth

how do the systems of the body work together? what function does this provide?
fully integrated in order to work together to maintain homeostasis
circulatory system functions
transport of materials between all cells of the body
digestive system functions
conversion of food into particles that can be transported into the body; eliminates waste
endocrine system functions
coordination of the body function through synthesis and release of regulatory molecules
immune system functions
defense against foreign invaders
integumentary system functions
protection from external environment
musculoskeletal system functions
support and movement
nervous system functions
coordination of body function through electrical signals and release of regulatory molecules
reproductive system functions
perpetuation of the species
respiratory system functions
exchange of oxygen and carbon dioxide between the internal and external environments
urinary system functions
maintenance of water and solutes in the internal environment; waste removal
what is the anatomical position?
body erect, feet slightly apart, arms at side, palms facing forward
superior
towards the head
inferior
towards the feet
anterior
towards the belly (bipedal)
posterior
towards the spine
medial
towards the midline
lateral
away from midline
proximal
close to
distal
far from
superficial
towards surface
deep
away from surface
sagittal
left and right parts
transverse
superior and inferior parts
frontal (coronal)
anterior and posterior parts
oblique
not at 90 degrees to body
mid
along the midline
para
away from the midline
serial
consecutive cuts along the plane
what is homeostasis
ability of the body to maintain a stable internal condition in respect to the changing external environment. Homeostasis does not mean equilibrium
what are the 4 components of homeostatic control
variable, receptor, control center, effector
receptor
takes in sensory information
control center
determines the set point and regulates the body’s response
effector
carries out the body’s response
variable
a factor in the body that can be modified by the effector
what is the negative feedback loop?
output shuts off the original effect of the stimulus or reduces its intensity
what is the positive feedback loop?
response enhances the original stimulus
