Intro to the Human Body Flashcards
Human Anatomy
Is the study of the body structure. Means to cut or cutting backwards ( putting things together from slices)
Human Physiology
Is the science of body functions. Including the study of homeostasis. ( keeping the organs systems of the body in balance)
Surface Anatomy
Is the study of form and markings of the body surface, often explored through visualization or palpating ( without any cutting)
Gross anatomy
Is the study of anatomical structures visible to unaided eye. After making the appropriate surface marking in the prior picture, the gross dissection proceeds through cutting.
Systemic Anatomy
Study all of the blood vessels, or all of the muscles, or all of the bones at once
Regional Anatomy
All anatomical structures of a specific region ( the thorax, or the head and neck) are all studied together.
Developmental anatomy
Is the study of the fertilized egg developing into its adult form
Embryology
Is a subcategory of developmental anatomy ( conception to 8th week of gestation)
Histology
Is the study of tissues
Cytology
The study of cellular strutures
Pathology
Is the study of anatomical changes due to disease
Autopsy
Is a postmortem (after death) examination of the body and internal organs performed by a pathologist.
An autopsy is usually done to:
Determine the cause of death
Identify diseases not detected during life
Determine the extent of injuries and contribution to death
Identify hereditary conditions
Cells
Are the basic structural and functional units of an organism
Tissues
Are groups of cells that work together to perform a similar function
What are the 4 basic types of tissues?
Epithelium
Connective tissue
Muscle
Nerves
Organs
Are structures composed of two or more different types of tissues ( all but the simplest of organs have all 4 basic tissues represented)
Organ System
Consists of related organs with a common function.
There are 11 organ systems in the body.
Organism
Consists of a collection of organ systems. Metabolism, responsiveness, movement, growth, differentiation, reproduction
Homeostasis
All parts of the body must be functioning together in a process
Metabolism
Is the sum of all catabolic ( breaking down and anabolic (building up) chemical processes that occur in the body.
Responsiveness
Is the body’s ability to detect and respond to changes which might represent an opportunity or a threat
above, top, toward head
superior
below, bottom, away from head
inferior
Toward the front
Anterior(ventral)
Toward the back
Posterior(Dorsal)
Toward the midline
Medial
Away from midline & body. (sides)
Lateral
Between medial and lateral
Intermediate
Nearest to the origination
Proximal
Farther from origination
Distal
Same side of the body
Ipsilateral
Opposite side of the body
Contralateral
Towards the surface
Superficial
Towards the core of the body
Deep
Pertaining to a covering over an organ
Visceral
Pertaining to a covering against a cavity wall
Parietal
Midline
Sagittal
Horizontal
Transverse
