Intro Flashcards
Positive feedback loop
Completes a dangerous process quickly to reestablish homeostasis
Example: blood clotting
Positive feedback
Initial signal provides a response that amplifies the original changes in conditions
Negative feedback
Response of the effector negates the stimulus
Distal
Away from the point of attachment
Proximal
Near the point of attachment to the trunks
Posterior
The back surface
Anterior
The front surface

Caudal
Homeostatic regulation
Adjustment of physiological systems to preserve homeostasis
Organism
Coordinates and integrates the functions of the organ system to maintain homeostasis
Homeostasis
Maintenance of a constant optimal internal environment
Physiology and types of physiology
Study of functions of the body Types: Cells Organs Systemic Pathological
Autoregulation
Automatic response in a cell, tissue, or organ to an environmental change
Medial
Toward the midline
Extrinsic regulation
The response controlled by the nervous system and the endocrine system
Anatomical position
Standing up with palms facing forward. I.e the reference point
Organelles
Specialized subunits within a cell that has a specific function
Molecules
2 or more atoms combined by a chemical bond
Atoms
The smallest part of an element that can’t be broken down by ordinary chemical reactions
Levels of organization
Chemical Cellular Tissue Organ Organ system Organism
Gross anatomy
Study of body parts visible to the naked eye Surface anatomy Regional anatomy Systemic anatomy Developmental anatomy
Anatomy and types of anatomy
Study of the structure. How it looks
Gross anatomy
Microscopic anatomy
Functions of cavities
Protect organs from shock or impact
Permit significant change in size and shape of internal organs
Microscopic anatomy and types
Study of structures we can’t see without a microscope
Cytology
Histology
