Ch 1 pt 1 Flashcards
Anatomy
Studies the form and structure of the body
Anatomy equals what
Structure/form
Physiology equals what
Function
The structure determines what
Function
Physiology
Examines how the body functions
Form and function are
Interrelated
Scientific method
Refers to a systematic and rigorous process by scientists
First step of the scientific method
Examine natural events through observation
Second step of the scientific method
Develop a hypothesis
Example of anatomy and physiology
Teeth
Example of the scientific method
Senses
Microscopic anatomy
Cells and tissues
The study of body cells and their internal structure
Cytology
The study of tissues
Histology
Gross/macroscopic anatomy
Investigates structures visible to the unaided eye
Studies the anatomy of each body system
Systemic anatomy
Examines the structures in a body region
Regional anatomy
Focuses on superficial anatomic markings and internal body structure
Surface anatomy
Examines anatomical similarities and differences in different species
Comparative anatomy
Studies developmental changes from conception to birth
Embryology
Examines macroscopic and microscopic anatomic changes resulting from disease
Pathologic anatomy
Investigates internal structures visualized by scanning procedures
Radiographic anatomy
Examine the function of body structures, focusing on the molecular and cellular level
Physiologists
Examines functioning of the heart, blood vessels, and blood
Cardiovascular physiology
Studies functioning of nerves and nervous system organs
Neurophysiology
Explores functioning of respiratory organs
Respiratory physiology
Investigates functioning of reproductive hormones and the reproductive cycle
Reproductive physiology
Focuses on the function of a body system during disease or injury to the system
Pathophysiology
Properties common to all organisms
Organization, metabolism, growth and development, responsiveness, regulation, reproduction
All organisms exhibit a complex structure and order
Organization
The sum of all chemical reactions that occur within the body
Metabolism
Small molecules joined to form larger ones
Anabolism
Large molecules broken down into smaller ones
Catabolism
Ability to sense and react to stimuli
Responsiveness
Organisms assimilate materials from environment; grow and develop
Growth and development
Ability to adjust internal bodily function to accommodate environment changes
Regulation
Ability to maintain body structure and function
Homeostasis
Produce new cells for growth, maintenance, and repair
Reproduction
Chemical level
Atoms and molecules
Cellular level
Cells, basic units of life
Tissue level
Similar cells performing common functions
Organ level
Multiple tissues working together
Organ system level
Related organs work together
Organismal level
Organ systems function together
Integumentary system
Skin, hair, nails, glands, and nerves
Skeletal system
Bones
Muscular system
Muscles
Nervous system
Nerves
Cardiovascular system
Heart, blood vessel
Endocrine system
Hormones
Lymphatic system
Organs, vessels, tissues
Respiratory system
Lungs
Urinary system
Bladder, kidney
Digestive system
Stomach
Anatomic position
Upright stance, feet parallel, upper limbs at the sides of the body, palms face towards the front
Slices of body are called
Sections or planes
Actual cut or slice that exposes internal anatomy
Section
Imaginary flat surface passing through body
Plane
Coronal (frontal) plane
Vertical plane dividing the body into anterior (front) and posterior (back) parts
Transverse (cross-sectional) plane
Horizontal plane dividing the body into superior (top) and inferior (bottom)
Midsagittal (median) plane
Vertical plane dividing the body into equal left and right sides
Sagittal plane
Parallel to midsagittal, but left or right of midsagittal; divides structure into unequal portions
Oblique plane
Passes through structure at any angle except hor. or ver.
Anterior
Front
Posterior
Back
Proximal
Closer to the specific limb
Dorsal
True back
Ventral
Belly front
Distal
Farther to the specific limb
Axial region
Anything besides arms and legs
Appendicular region
Arms and legs
