Human organism Flashcards
What word means dissect or cut apart and separate the parts of the body for study
“anatomy”
What are two basic approach to the study of anatomy
SYSTEMATIC anatomy
REGIONAL anatomy
The scientific discipline that investigates the structure of the body
Anatomy
Type of approach to the study of anatomy-study of body by system
*pagka sunod-sunod ng parts ng nervous system
Systematic anatomy
Type of basic approach to the study of anatomy- the study of the Organization of the body by areas
Regional anatomy
To general ways to examine the Internal structures of a person
Surface Anatomy
Anatomical imaging
General ways to examine Internal structures of a person- the study of external features such as bony projection which serves as landmarks for locating deeper structures
Surface anatomy
General ways to examine the internal structures of a living person – involves the use of x-rays, ultrasounds, magnetic resonance imaging(MRI)
Anatomical imaging
Is the scientific discipline that deals with the processes or functions of living things
Refers to how the bodywork
Physiology
Types of microscopic anatomy
Cytology and histology
Traces structural changes throughout life
Developmental anatomy
Levels of organization
Atom– Cell– tIssues – Organ – organ system – organism
Characteristics of life
Organization, metabolism, responsiveness, growth, development, reproduction
Ability to consume fuel and break it down
Metabolism
Refers to specific interrelationship among the parts of an organism and how those parts interact to perform specific functions
organization
Ability to respond to stimuli
Responsiveness
Refers to an increase in size of all or part of the organism
Growth
Includes the changes an organism undergoes through time
Development
Ability to multiply
reproduction
Maintaining the balance of the body
Homeostasis
Two types of stimuli
External and internal
A type of feedback that puts back the balance in homeostasis. Example shivering
Negative feedback
A type of stimuli that pushes further the stimuli
Positive feedback
Produces a change to a variable (the factor being regulated)
Stimulus
Detects the change; Monitors the environment and responds to change
Receptor
Two types of Path ways of the nerve impulses in the homeostatic control
Afferent and efferent pathways
A type of path way that Carry nerve impulses into the central nervous system
Afferent pathways
A type of pathways that Carry nerve impulses away from central nervous system to effectors
Efferent pathways
Information travels along the afferent pathways to the control center
Input
Determines the appropriate response and course of action
Processes the stimulus received
Control center
Information sent from the control center travels down the efferent pathway to the effector
output
From the Effector; Balances out the original stimulus to maintain homeostasis
Response
A position where a person lying face up.
Supine position
Position where person lying face downward
prone position
