Seven approaches

Name the 7 approaches to studying the body.

1. Body planes & directions
2. Body cavities
3. Quadrants & regions
4. Anatomy & physiology
5. Microscopic-to-macroscopic
6. Body systems
7. Medical specialties

What is the coronal (frontal) plane?

Vertical plane dividing the body into front (anterior) and back (posterior) sections

What does anterior (ventral) mean?

Front of the body

What does posterior (dorsal) mean?

Back of the body

What is the prone position?

Lying face-down (anterior side down)

What is the supine (dorsal) position?

Lying on your back (posterior side down)

What is the sagittal plane?

Vertical plane dividing the body into right and left sections

What is a midsagittal plane?

Divides the body into equal right and left halves

What is a parasagittal plane?

Divides the body off the midline

What is the transverse plane?

Horizontal plane dividing the body into upper (superior) and lower (inferior) sections

Medial

Toward the midline

Lateral

Away from the midline

Superior (cephalad)

Toward the head

Inferior (caudad)

Toward the tailbone

Proximal

Closer to where a limb attaches to the body

Distal

Farther from where a limb attaches

Superficial (external)

On the surface of the body

Deep (internal)

Inside the body

What is a body cavity?

A hollow space surrounded by bone or muscle

Cranial cavity contains what?

The brain

Spinal cavity contains what?

Spinal cord, spinal nerves, spinal fluid

Thoracic cavity contains what?

Lungs

What separates the thoracic and abdominal cavities?

The diaphragm

What cavities make up the abdominopelvic cavity?

Abdominal + pelvic cavities

What are the four abdominal quadrants?

RUQ, LUQ, LLQ, RLQ

How many abdominal regions are there?

Nine regions

Name 3 abdominal regions.

Epigastric, umbilical, hypogastric (others include hypochondriac, lumbar, inguinal)

Anatomy

Study of body structure

Physiology

Study of body function

What is microscopic?

Structures seen only with a microscope

What is macroscopic?

Structures visible to the naked eye

Order from smallest to largest.

Cells → tissues → organs → body systems

Oncology

Study and treatment of cancer

Psychiatry

Study and treatment of the mind

Pediatrics

Study and treatment of infants and children

Geriatrics

Study and treatment of the elderly

Pharmacology

Study of drugs used as medicines
