complete name of instructor
Daniel Dominick G Te
study of embryonic development
Embryology
study of the complete development of an individual from fertilization to death ?
Developmental Biology
study if cellular structure and functions
Cell biology
study of microscopic structure of tissues
Histology
study of structured that can be examined without a microscope
Gross Anatomy
study of structure of specific systems of the body such as the nervous or respiratory
Systemic Anatomy
Study of specific regions of the body such as the head or chest
regional anatomy
study of surface markings of the body to understand internal anatomy through visualization and palpitations
surface anatomy
study of internal body structures that can be visualized with techniques such as x-rays, MRI, CT-scan, and other technologies for clinical analysis
imaging anatomy
study of structural changes associated with disease
pathological anatomy
study of functions of individual molecules such as proteins and DNA
Molecular physiology
study of functional properties of nerve cells
Neurophysiology
study of hormones and how they control body functions
endocrinology
study of functions of the heart and blood vessels
Cardiovascular physiology
Study of the body defenses against disease-causing agents
Immunology
study of functions of the air passageways and lungs
respiratory physiology
study of functions of the kidneys
Renal physiology
study of the changes in the cell and organ functions due to physical activity
Exercise physiology
study of functional changes associated with disease and aging
Pathophysiology
the very basic level which includes atoms, the smallest units of matter that participate in chemical reactions, and molecules, two or more atoms joined together
Chemical level
molecules combine to form cells, the basic structural and functional units of an organism that are composed of chemicals
Cellular level
groups of cells and the materials surrounding them that work together to perform a particular function
Tissue level
different types of tissues are joined together that have specific functions and usually have recognizable shapes
Organ level
consists of related organs with a common function
System level
any living individual; all the parts of the human body functioning together constitute the total organism
Organismal level
Level Of Structural organization (7 steps)
Atom - Molecule - Cell - Tissue - Organ - Organ System - Organism
sum of all chemical processes that occur in the body
Metabolism
types of chemical processes that occur in the body (2pts)
Catabolism and Anabolism
body’s ability to detect and respond to changes
Responsiveness
motion of the whole body, individual organs, single cells, and even tiny structures inside cells
Movement
increase in body size that results from an increase in the size of existing cells, an increase in the number of cells, or both
Growth
development of a cell from an unspecialized to a specialized state
Differentiation
refers either to the formation of new cells for tissue growth, repair or replacement, or the production of a new individual
Reproduction
is the maintenance of relatively stable conditions in the body’s internal environment
Homeostasis
Occurs because of the ceaseless interplay of the body’s regulatory systems, and is a dynamic condition
Homeostasis
An important aspect of _______________ is maintaining the volume and composition of body fluids
Homeostasis
The body can regulate its internal environment through what ?
Many feedback systems
It is a cycle of events in which the status of a body condition is monitored, evaluated, changed, remonitored, re-evaluated, and so on
Feedback System
what do you call a monitored variable?
controlled condition
any disruption that changes a controlled condition
Stimulus
monitors changes in a controlled condition and sends input to a control center
Receptor
sets the narrow range or set point within which a controlled condition should be maintained
Control Center
receives output from the control center and produces a response or effect that changes the controlled condition
Effector
