Chapter 1 Vocabulary Flashcards
Developmental anatomy
•structural changes that occur between conception and birth
Anatomy
Parts
Embryology
8th week and earlier
Two MICRO subjects in anatomy and physiology:
- cytology
* histology
Cytology
Study of cells
Histology
Study of tissue
Two MACRO subjects of study
Gross anatomy
Surface anatomy
• no microscope necessary
Gross anatomy
Internal structure
Without microscope
Surface anatomy
External structure
Physiology
Process and function
5 topics of physiology
- cellular
- systemic
- neuro
- cardio
- exercise
Cellular processes are
•examines processes occurring in cells
Systemic physiology
•considers functions of organ systems
Neurophysiology
•focuses on nerve system
Cardiovascular physiology
•deals with the heart and blood vessels
Pathology
•deals with disease and disfunction
6 levels of organization
- chemical
- cellular
- tissue
- organ
- organ system
- organism
Chemical level of organization
- interactions between atoms
- makes molecules
- function relates to structure
Cellular level of organization
- basically structural and functional units of living organisms
- molecules make up organelles, organelles make cells
Tissue level of organization
- made of similar cells
* surrounding cells determine function of tissue
Organ level of organization
Tissue combine to create organ
Organ system level of organization
•organs combine to make organ system
Organism level of organization
•any living thing considered as a whole
6 characteristics of life
- organization
- metabolism
- responsiveness
- growth
- development
- reproduction
Organ systems of the body:
- integumentary
- skeletal
- muscular
- lymphatic
- respiratory
- digestive
- nervous
- endocrine
- cardiovascular
- urinary
- reproductive
Integumentary
•skin: protection, prevents water loss
Skeletal
•protections and support
Muscular
- produces body movements
- maintains posture
- produces body heat
Lymphatic
•removes foreign substances from the blood
Respiratory
•exchanged O2 and CO2 between blood and air
Digestive
- chemical and mechanical processes of digestion
- nutrients absorption
- elimination of waste
Nervous
- regulatory system
- physiological processes
- intellectual functions
Endocrine
•regulatory
Influences: metabolism, growth, reproduction
Cardiovascular
- transports nutrients, waste, gases and hormones through body
- immune response
Urinary
- pH balance
- ion balance
- water balance
Female reproductive system
- oocyte production
* site of fertilization and fetal development
Male reproductive system
- sperm reproduction
* sperm transportation
Set point range
•ideal normal value that maintains homeostasis
Normal range
•fluctuation around the set point, maintaining homeostasis
Negative feedback
•brings values back to set point
Positive feedback
- moves variable away from set point
- responses aren’t homeostatic
- positive implies when value deviates from norm, system makes deviation greater
Anatomical position
- erect
* palms forward
Supine
•face up
Prone
•face down
