- Cell
- tissue
- organ
- organ system
- organism
Gross anatomy
Things we can see with the naked eye
Gross anatomy:
- surface anatomy (define)
Study of the general form and superficial markings
Gross anatomy:
- Regional anatomy (define)
Study of all of the superficial and internal features in a specific region of the body
Gross anatomy:
- Systemic anatomy (define)
study of the structure of major organ systems
Microscopic anatomy
things we nee magnification to see
types of anatomy that fall under Gross anatomy
- surface anatomy
- regional anatomy
- systemic anatomy
Types of anatomy that fall under microscopic anatomy
- Cytology anatomy
- histology anatomy
Microscopic anatomy:
- cytology (define)
study of the structure o f individual cells
Microscopic anatomy:
- Histology anatomy (define)
study of the tissue level of anatomical organization
List all of the body systems (12)
- Integumentary system
- Skeletal system
- Muscular system
- vascular system
- lymphatic system
- nervous system
- respiratory system
- digestive system
- endocrine system
- Renal/Urinary system
- Male Reproductive system
- Female reproductive system
Homeostasis
The body likes things to stay the same, and will adjust to keep things that way
Negative feedback
occurs when making a change sends a signal to undo the change
what is the anatomic position?
Standing upright arms down and palms forward, feet together
Appendicular
direction
means arms and legs ( the “appendages”)
Axial
Direction
means Trunk of the body (so everything except the arms and legs)
Anterior
Direction
means front
Posterior
Direction
means back
Ventral
Direction
means toward the chest and belly
Dorsal
Direction
means toward the back
Superior
direction
means up
inferior
direction
means down
Cephalic/cranial
Direction
means towards the head
Caudal
Direction
means towards the buttocks
superficial
Direction
near the surface of the body and can come in contact with things outside the body
Ex: rib cage is superficial to the heart
Deep
Direction
farther from the surface of the body
Ex: rib cage is deep to the pectoral muscles
External
direction
closer to the outside
internal
direction
more on the inside
proximal
direction
closer to the center
(mainly used for arms and legs)
distal
direction
further form the center
(mainly used for arms and legs)
lateral
direction
further out to the sides
medial
direction
closer to the center
supine
direction
body positioned face up
drink soup fine
Prone
Direction
body positioned face down
Soup “Prones” out of your mouth
Transverse plane
Horizontal cut
Sagittal plane
cuts the body into left and right halves
midsagittal/median plane
means the cut is right down the middle
Parasagittal plane
means we’re making a sagittal cut (into right and left), but it’s not right down the middle
Coronal/frontal plane
cuts the body into a front half and a back half
oblique plane
cuts the body at an angle
