Section 4 (Ch. 7 & 8)

Question 1

Physiological Systems

Answer 1

Organ systems within the body; NS, cardiac, musculoskeletal.

Question 2

Theoretical Bridge

Answer 2

The connection between two different variables.

Question 3

Electrodes

Answer 3

Sensors usually placed on the surface of the skin and linked to a physiological recording machine to measure physiological variables.

Question 4

Telemetry

Answer 4

The process by which electrical signals are sent from electrodes to a polygraph using radio waves instead of wires.

Question 5

Automatic Nervous System (ANS)

Answer 5

Part of peripheral NS, connects to vital bodily structures associated with maintaining life and responding to emergencies. Sympathetic and parasympathetic.

Question 6

Electrodermal Activity

Answer 6

Galvanic skin response or skin conductance.
Electricity will flow across the skin with less resistance if that skin is made damp with sweat. Sweating palms activated by SNS; therefore, it is a way to measure changes in the SNS.

Question 7

Skin Conductance

Answer 7

The degree to which skin carries (conducts) electricity, depends on amount of water present in the skin.
