List all of the body systems (12)
- Integumentary system

- nervous system
- respiratory system
- digestive system
- endocrine 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

Body cavities
- empty spaces in your skeleton that your organs go into
- Closed, full of fluid, and lined with a thin layer of tissue called serous membrane
serous membrane
thin layer of tissue in body cavities
Visceral organ

List some visceral organs
- Brain and spinal cord
- lungs
- heart
- stomach
- spleen
- liver
Dorsal cavity
Contains brain and spinal cord
made of 2 parts:
- Cranial cavity: contains brain
- vertebral cavity: contains spinal cord
Contains brain and spinal cord
Made of 2 parts
Dorsal cavity
- Cranial cavity: contains brain
- vertebral cavity: contains spinal cord
Thoracic Cavity
Inside the ribcage Contains: - Pleural cavities: contain the lungs - Pericardial cavity: contains the heart - Mediastinum
Cranial cavity
Contains brain
Vertebral cavity
Contains spinal cord
Pleural Cavities
Contains the lungs
Pericardial Cavity
Contails the heart
Mediastrinum
not really a cavity, it contains the big arteries and veins that go to the heart, the trachea, and the esophagus. Also surrounds and stabilizes the pericardial cavity
