18
Q

What happens when conditions in the body are not maintained

A

Homeostatic imbalance/ illness

19
Q

What are the 2 ways homeostasis can be regulated

A
  1. Intrinsic regulation 2. Extrinsic Regulation
20
Q

Homeostasis is regulated by

A

feedback mechanisms

21
Q

Intrinsic regulation

A

Cell, tissue, or organ responds to change automatically

22
Q

Extrinsic regulation

A

nervous or endocrine system initiates change throughout the body

23
Q

What are the 3 parts of a feedback mechanism

A
  1. Receptor 2. Control Center 3. Effector
24
Q

Receptor

A

A sensor that responds to a particular stimulus/ change

25
Q

Control Center

A

Receives/ processes input from receptors, determines body’s normalcy, sends out commands

26
Q

Effector

A

Cell or organ that responds to commands from control center

27
Q

What are the 2 types of feedback mechanisms

A
  1. Negative feedback 2. Positive feedback
28
Q

Negative feedback

A

mechanism opposes the stimulus

29
Q

Positive feedback

A

mechanism enhances the stimulus until climactic event occurs

30
Q

What is an example of negative feedback

A

blood glucose

31
Q

What is an example of positive feedback

A

Uterine contractions

32
Q

What are the characteristics of Standard Anatomical Position

A
  1. Standing 2. Anteriorly facing 3. Palms forward
33
Q

Internal organs are housed within enclosed

A

spaces or cavities

34

35
Q

The dorsal cavity contains what two cavities

A
  1. Cranial Cavity 2. Vertebral Cavity
36
Q

The ventral cavity contains what two cavities

A
  1. Thoracic 2. Abdominopelvic
37
Q

The thoracic cavity houses what two cavities

A
  1. Pleural (lungs) 2. Mediastinum (heart and thyamus)
38
Q

The abdominopelvic cavity houses what two cavities

A
  1. Abdominal (stomach and intestines) 2. Pelvic (bladder)
39
Q

Subdivisions of the ventral body cavity are lined with

A

serous membranes

40
Q

What are the 2 layers of serous membranes

A
  1. Parietal 2. Visceral
41
Q

Parietal layer

A

lines internal surface of body wall

42
Q

Visceral layer

A

covers external surface of organs

43
Q

What is an example of a serous membrane

A

pericardium (around the heart)
