Median means two equal halves

Ex: Radiograph

24
Q

A

Divided from top to bottom or cross section (superior and inferior sections)

Ex: CAT Scan of the head

25
Q

Words used interchangeably with Anterior and Posterior

A

Ventral and Dorsal

26
Q

Posterior Cavity

A

Also called Dorsal Cavity - Back of body

Contains two divisions (cranial and vertebral)

27
Q

Cranial Cavity

A

Part of larger Dorsal or Posterior cavity

Brain/Skull

28
Q

Vertebral cavity

A

Part of larger Dorsal/Posterior cavity

Spinal Chord/Vertebral bones

29
Q

Ventral Body Cavity

A

Towards the front of the body

Contains Thoracic and abdominopelvic cavities

30
Q

Thoracic Cavity

A

Chest (superior to diaphragm)

  1. Left pleural
  2. Mediastinal
  3. Right pleural
31
Q

Left Pleural Cavity

A

In thoracic cavity

Left Lung

32
Q

Mediastinal Cavity

A

Within the thoracic cavity

Contains esophagus, trachea and large vessels

Also contains Pericardial Cavity (heart)

33
Q

Pericardial Cavity

A

Within the Mediastinal cavity that is within the thoracic cavity that is within the Ventral Cavity

Contains the Heart

34
Q

Right pleural cavity

A

Contains right lung

35
Q

Abdominopelvic Cavity

A

Upper body (inferior to the diaphragm)

Contains abdominal and pelvic cavity

36
Q

Abdominal Cavity

A

Contains organs in the belly (stomach, spleen, pancreas and intestines)

Can be divided into four quadrants (drawn opposite on diagram for easier reference to body)

37
Q

Right upper quadrant of abdominal cavity

A

Contains liver, pancreas and gallbladder

38
Q

Left upper quadrant of abdominal cavity

A

Contains stomach, spleen and part of pancreas

39
Q

Contained in both upper quadrants of abdominal cavity

A

Pancreas

40
Q

Right lower quadrant of abdominal cavity

A

Contains cecum, appendix, part of intestine and ascending colon

41
Q

The left lower quadrant of the abdominal cavity

A

Contains the descending & sigmoid colon and distal large intestine

42
Q

Contained in all four quadrants of abdominal cavity

A

Small and large intestines

Large intestines surround the small intestines like a picture frame

43
Q

Pelvic cavity inside abdominal cavity

A

Reproductive, urinary (not kidneys though) and terminal digestive tract below abdominal cavity

Also, sigmund colon, rectum, anus, bladder snd uretha

44
Q

Homeostasis

A

Normal function
Equilibrium or balance

Involves organs and nervous system and endocrine system

45
Q

Negative feedback in physiology

A

Control mechanism

Decreases or shuts off stimulus (to get back to homeostasis)

Ex: Temperature regulation

46
Q

Sensory Receptor

A

Monitors internal environment and responds to changes

Detects stimulus : change in external environment causing internal changes

47
Q

Control Center

A

Analyzes the information received snd determines a response

Get to a normal set point

48
Q

Effector

A

Provides means for regulatory center’s response

Pathway relays messages from the regulatory center to the effector

49
Q

Positive feedback

A

Accelerate a stimulus

Keeps moving away from normal

50
Q

What is the mechanism of homeostasis?

A

Negative feedback (moves things back to normal)

51
Q

What does the control center contain?

A

Contains the set point for the variable

52
Q

What does the receptor do?

A

Detects the variable

53
Q

What does the effector do?

A

Responds to bring the variable back to homeostatic levels
