Anatomy lecture- Exam 1 (Ch. 1) Flashcards
Cytology: the study of cells
Histology: the study of tissues
microscopic anatomy
study of structures visible to the unaided eye
gross anatomy (macroscopic anatomy)
refers to the superficial anatomical markings & relationship to deeper structures
surface anatomy
changes that occur during illnesses
clinical anatomy
studies anatomical landmarks important for surgical procedures
surgical anatomy
traces structural changes that occur in the body over time
developmental anatomy
anatomical similarities & differences between types of animals typically vertebrates
comparative anatomy
shared derived traits; all members of a group have that trait
synapomorphies
- dorsal hallow nerve cord
- notochord
- post-anal tail
- pharyngeal arches
- braincase
vertebrate synapomorphies
4 elements of the body
hydrogen, oxygen, carbon, nitrogen
molecular composition
water (66%), proteins (20%), lipids (10%), carbohydrates (3%), other (1%)
smallest living unit; have organelles
cellular level
cells & some surrounding material
tissue level
combination of tissues
organ level
combination of various organs
(heart & blood vessels = cardiovascular system)
organ system level
(1) order
(2) regulation
(3) growth and development
(4) energy processing
(5) response to the environment
(6) reproduction
(7) evolutionary adaptation
characteristics of life
internal and external; respond to changes via acute or chronic adjustments; homeostasis
responsiveness
increase in size of cells
hypertrophy
increase in number of cells
hyperplasia
cells with particular functions
differentiation
anabolism, catabolism, absorption, respiration, excretion
metabolism & excretion: chemical reactions
synthesis of complex molecules
anabolism
breakdown of complex molecules
catabolism
process of bringing material into body
absorption
