Divides the body into equal left and right halves.
What is midsagittal?
100
State the systems corresponding to the following...
heart, liver, pituitary gland, kidneys, skin
What are cardiovascular, digestive, endocrine, urinary, and integumentary?
200
This level exists in singular as well as multiple forms.
This is the division between living vs nonliving levels.
What are cells?
200
Cranial and Spinal are subdivisions of the ______ cavity
What is the dorsal cavity?
200
The wrist is _______ to the elbow, no matter what position the arm is in.
What is distal?
200
A separation along this plane would keep the face intact.
What is the frontal (also called coronal) plane?
200
Explain how thermoregulation is an example of homeostasis, and whether this is negative or positive feedback.
Thermoregulation is the maintenance of stable internal body temperature even though environmental temperature varies. This is negative feedback because the response opposes the initial disturbance. As environmental temp. increases our homeostatic mechanisms work to keep our internal temp within normal limits (decrease).
300
When cells work together for a common function.
What are tissues?
300
Thoracic and abdominopelvic are subdivisions of the ....?
What is the ventral body cavity?
300
The skeleton is ______ to the skin.
What is deep?
300
The amputation of a limb below the patellar region would be a division along this plane.
What is the horizontal plane?
300
Explain the relationship between the following:
receptor/sensor, control center, effector
The receptor/sensor receives the stimulus (change in temp) and sends it to the control center (brain). The control center integrates the response and sends it to effectors (muscles, glands).
400
When tissues work together for a common function they form...?
What is an organ
400
Divides the ventral body cavity. State the cavities divided by this structure.
What is diaphragm? Divides the thoracic from the abdominopelvic.
400
The nose is _____ to the face.
What is anterior?
400
These planes are parallel.
What is sagittal and midsagittal?
400
The homeostatic mechanism of EXTRINSIC regulation occurs when the ___ and ____ systems act together to control or adjust other systems.
What are the nervous and endocrine systems?
500
The levels of organization in ascending order.
What is chemical, cellular, tissue, organ, organ system, organism?
500
The heart and lungs are found in _____ and _____ cavities.
What are the mediastinum (heart) and pleural (lungs) cavities?
500
The ventral body cavity is closer to the ______surface of the body and the dorsal body cavity is closer to the ____ surface.
What is anterior and posterior?
500
State the names of four planes and show us where they are found.
What are the sagittal, midsagittal, frontal (coronal), and horizontal planes?
500
Name an effector that responds to increased or decreased body temperature and explain how the terms vasodialation and vasoconstriction relate to the effector.
Superficial blood vessels are one example of effectors that respond to temperature.
Vasodialation and vasoconstriction relate to increased and decreased diameter of blood vessels. Vasodialation helps to dissipate excess body heat. Vasoconstriction helps to conserve needed body heat.
