What is Control Center?

determines set point; receives input from receptors

Gross or macroscopic anatomy is studying

regional, systemic, and surface anatomy

maintenance of relatively stable internal conditions

study of structure of body parts and their relationship to one another

monitors environment and responds to stimuli

What is the correct order of the Levels of structural organization?

chemical, cellular, tissue, organ, organ system, organismal

factors which tend to fluctuate (blood sugar, body temp, blood volume, etc.

Answers

1
Study of function of body parts; how they work to carry out life-sustaining activities
organ systems
subdivisions
physiology
anatomy
2
What is Control Center?
changes controlled variables
monitors environment and responds to stimuli
receives output from control center
determines set point; receives input from receptors
3
Subdivisions of anatomy are: Gross or macroscopic, microscopic, and developmental
True
False
4
Gross or macroscopic anatomy is studying
cytology and histology
embryology
physiology
regional, systemic, and surface anatomy
5
Positive feedback (PFBM) response does not enhance or exaggerate original stimulus
False
True
6
Negative feedback (NFBM) is the most-common FB mechanism in body
True
False
7
Positive feedback (PFBM) does all except for one
usually controls infrequent events
enhances labor contractions; blood clotting
exhibits amplifying effect which causes variable to go in same direction
maintains body fluids
8
Interdependency is not when systems rely on one another for many different things and cannot function without the other
False
True
9
What is Homeostasis?
maintenance of relatively stable internal conditions
maintenance of relatively unstable external conditions
maintenance the digestive system
maintenance of NFBM
10
Developmental anatomy is not the study of embryology
False
True
11
Body must be constantly be monitored and regulated to maintain homeostasis
False
True
12
What is Anatomy?
microscopic
study of function of body parts; how they work to carry life activities
gross or macroscopic
study of structure of body parts and their relationship to one another
13
Negative feedback (NFBM) does all except for one
variable changes in opposite direction
reduces and shuts off original stimulus
maintains equilibrium
regulates body temp and blood glucose concentration
14
Anatomy and physiology are not inseparable
True
False
15
Microscopic anatomy is studying
gross or macroscopic
developmental
embryology
cytology and histology
16
What is Receptor?
receives output from control center
receives input from receptors & determines appropriate response
determines setpoint at which variable is maintained
monitors environment and responds to stimuli
17
What is the correct order of the Levels of structural organization?
cellular, chemical, tissue, organ, organismal, organ system
chemical, tissue, cellular, organ, organismal, organ system
chemical, cellular, tissue, organ, organ system, organismal
organismal, cellular, tissue, organ, organ system, chemical
18
Homeostatic control of variables involve Receptor, Control Center, and Effector
False
True
19
What are variables?
maintain body temperature
factors which tend to fluctuate (blood sugar, body temp, blood volume, etc.
regulate interdependency
factors of the endocrine system
20
How many organ systems are in the human body?
