Homeostasis, Body Cavities, and Body Regions

Which is the correct structural order?

• tissue-cells-organ-organ system
• cells-tissue-organ system-organ
• tissue-cells-organ system-organs
• cells-tissue-organ-organ system

The cranial cavity and the spinal (vertebral) cavity are both contained within the _______ cavity.

• dorsal
• ventral
• abdominal
• throacic

Which of the following is an example of positive feedback to indirectly maintain homeostasis?

• the chemical reactions involved in blood clotting
• your blood vessels dilate and you begin to sweat in response to elevated body temperature
• your blood vessels constrict and you begin to shiver in response to low body temperature
• your coach compliments you on your performance in practice

Which of the following descriptions are involved in negative feedback?

• deviation from a set point
• causes changes to compensate for deviation in order to maintain homeostasis
• constantly monitors conditions
• All of these are involved in negative feedback

Humans have ___ for body temperature, blood glucose concentrations, electrolyte concentrations, pH levels, tendon tension and variables.

• positive feedback mechanisms
• set points
• a wide internal range
• no regulation

Homeostasis

• allows for a wildly fluctuating internal environment
• is impossible in vertebrates
• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation

Homeostasis in the human body is often maintained by a: 

• neutral feedback loop 
• solar feedback loop
• positive feedback loop
• negative feedback loop

Positive feedback is when the change caused by the stimulus is

• decreased
• non existant
• increased
• changes constantly

What are the definitions for anatomy anatomy and physiology?

• Anatomy=function
  Physiology=structure
• Anatomy = structure
  Physiology = function

This term refers to the shoulder region

• brachial

• acromial

• unilateral

• carpal
