Cavities
what is located in the mediastinum (5)
(heart, trachea, esophagus, thymus, blood vessels)
towards the head, towards the feet
Superior, inferior
Understanding what is essential in ultrasounds, CT scans, MRI any type of radiography
Body planes
portion of body w head neck torso/trunk
axial
what 2 cavities are located in the dorsal cavity
cranial and spinal
Upper ventral cavities include (3)
Thoracic, Mediastinum, Pleural
Front and back (4)
anterior, posterior
ventral, dorsal
sagittal
body portion consists of upper and lower extremities
appendicular
what is located in the pelvic cavity
repro organs, urinary bladder, and lowest part of intestine
what separates the thoracic cavity from the abdominopelvic cavity
diaphragm
Towards the midline and
toward the side of body or away from midline
Medial, lateral
Divides the body lengthwise into two EQUAL halves
midsagittal plane
basic type of control system in the body
feedback loop, Negative FL understand this concept
sensor detects change (temp)
feeds back to control center (thermostat)
effector makes change (turns on heater)
The effector has an effect on the regulated condition
what is located in the thoracic cavity
Mediastinum - heart/trachea
Pleural - lungs
what makes up the dorsal cavity
Cranial and spinal cavities
towards or nearest the trunk of body or nearest the point of origin of one of its parts and
away from or farthest from the trunk or the point of origin of a body part
Proximal/Distral
lengthwise running side to side
frontal
Structural Levels of Organization (5)
chemical
cell
tissue
organ
system
what does the abdominal cavity contain
stomach, intestines, liver, gallbladder, pancreas, spleen
What is located in the abdominal cavity (7)
liver, gallbladder, stomach, spleen, pancreas, sm intestine, parts of lrg intestine
near the surface and farther away from body surface
superficial and deep
horizontal or crosswise plane
transverse
Examples of each level
chemical, atom
cell, neuron
tissue, org of cells to perform a fx
organs, tissues act together as a unit for fx
systems, same as above but more complex
what does the pelvic cavity contain
Repro organs, urinary bladder, lowest portion of intestines
