Basic anatomy Flashcards
Anatomy
Study of the structure and relationship between body parts
Physiology
Study of the function of body parts and the body as a whole
Gross Anatomy
Study of body parts visible to the naked eye
Histology
Study of tissues at the microscopic level
Cytology
Study of cells at the microscopic level
Neurophysiology
Study of how the nervous system functions
Cell
Smallest unit of life
Homeostasis
Maintenance of stable, internal conditions within specific limits
Organelles
Specialized bodies within the cell that perform specific cellular functions
Tissue
Group of similar cells performing a common function
Organ
Group of different kinds of tissues working together to perform an activity
Organ System
Two or more organs working together to perform an activity
Organism
System possessing the characteristics of living things
includes the cranial cavity (includes brain), and the vertebral cavity (includes spinal cord).
Posterior/Dorsal body cavity
includes the thoracic cavity (includes lungs and heart), and the abdominopelvic cavity (includes the digestive organs, bladder, and reproductive organs).
Anterior/Ventral body cavity
region refers to main axis of the body – head, neck, and trunk.
Axial Skeleton
region refers to the appendages – arms and legs
Appendicular Skeleton
_______ is the tendency of the body to seek and maintain an internal stability when dealing with external changes
Homeostasis
Negative feedback is ________
a sensing mechanism that detects change in conditions beyond specific limits.
Positive feedback is__________
the variant condition is intensified so that it is driven beyond normal limits – this is uncommon but does occur during:
Blood clotting
Childbirth
Sexual orgasm
Which of the following planes divides the body vertically into anterior and posterior parts?
Sagittal Planes
Dorsal Body Cavity
Axial Region
Frontal Planes
Frontal planes divide the body into anterior and posterior parts while sagittal planes divide the body into right and left parts.
