Ch 1

Question 1

Cytology

Answer 1

Study of body cells and internal structure

Question 2

Histology

Answer 2

Study of tissues

Question 3

Systemic anatomy

Answer 3

Studies anatomy of each functional body system

Question 4

Regional anatomy

Answer 4

Studies structures in particular region

Question 5

Surface anatomy

Answer 5

Superficial an atomic markings and internal body structures

Question 6

Levels of organization

Answer 6

Chemical
Cellular
Tissue
Organ
Organ system
Organismal

Question 7

Homeostasis

Answer 7

Ability of an organism to maintain consistent internal environment or “steady state” in response to changing internal or external conditions

Question 8

Receptor

Answer 8

Detects changes in variable

Question 9

Control center

Answer 9

Interprets input from reception and initiates change through effector

Ex. Nervous system can provide quicker response

Question 10

Effector

Answer 10

Structure that brings about changes to alter the stimulus

Question 11

Negative feedback

Answer 11

Controls most processes in body

Variable fluctuates within a normal range around a SET POINT

HOMEOSTATIC CONTROL RESPONDS TO VARIABLE IN OPPOSITE DIRECTION TO BRING NORMAL RANGE

Stimulus increases, effector decrease variable

Stimulus decrease, effector increase variable

Question 12

Components of homeostatic control mechanism

Answer 12

1. Stimulus (changes in variable)
2. Receptor (detects stimulus)
3. Receptor sends input info
   4.Control center
4. Control center sends output info
5. Effector
   Homeostasis is restored

Question 13

Normal ranges for Clinical Practice

Answer 13

Temp 98.6
Sugar 80-110 mg/dL
BP 90-120/60-80 mm Hg

Question 14

Diagnosis

Answer 14

Specific cause for homeostatic imbalance
