Human Body & Orientation Ch. 1 Flashcards
Anatomy v. Physiology
- anatomy the study of the body structure and its morphology
- anatomy the study of the structure of the human body
- includes morphology (which is the study of form)
-Physiology- the study of the body function
Atomic/molecular level
Cellular level
Tissue Level
- atoms from molecules
- cells and their functional subunits
- a group of cells performing a coordinated function
- Organ level
- Organ system
- Organism level
- Population level
- Ecosystem
- a discrete structure made up of more than one tissue type
- organs working together for a common purpose (i.e heart & blood vessels, uterus, & bladder)
- the result of all organ systems working in coordination
- interaction with other Homospaiens
- interaction with other species in our ecosystems
Axial v. Appendicular
Axial- the main axis of the body (basically the head and the body trunk)
Appendicular - the limbs (legs and arms)
Frontal (coronal) plane
-lies vertically and divides the body in the posterior and the anterior
(cutting the head through the ears way)
Median (midsagittal) plane
-specific sagittal plane that lies vertically in the midline
cutting head nose way
Transverse plane
-runs horizontally and divides body into superior and inferior parts
(cutting body waits way)
Dorsal body cavity
- cranial cavity
- vertebral cavity
Ventral body cavity
- thoracic cavity
- abdominal cavity
- pelvic cavity
Inner tube
-extends from mouth to anus and includes the pharnyx, respitory and digestive organs, the pharynx, respitory and digestive organs, the
Outer tube
-consists of axial skeleton and associated axial muscles that make up the outer body wall and nervous structures
Standard Anatomical Position
-person stands erect with feet together and eyes forward, palms face anteriorly with the thumbs pointed away from the body
Anterior thoracic (axial)
- axillary
- sternal
- mammary
Anterior cephalic (head) (axial)
- frontal
- orbital
- nasal
- oral
- mental
Anterior Abdominal (axial)
Umbilical
