The point in a set where you can’t life one more rep without sacrificing form

Question 9

RPE

Answer 9

Rated perceived exertion: measures the intensity of an exercise

Question 10

Carotid pulse site

Answer 10

Carotid arteries: supply the head and neck with oxygenated blood. Pulse site is next to the larynx

Question 11

Radial pulse site

Answer 11

Pulse site in the wrist

Question 12

Apical pulse site

Answer 12

Over the apex of the heart (left side of the chest)

Question 13

Temporal pulse site

Answer 13

Temple area

Question 14

Dyspnea

Answer 14

Difficulty breathing or shortness of breath

Question 15

Insulin

Answer 15

Insulin helps store the sugar in your liver and releases it when your blood sugar level is low. Therefore, insulin helps balance out sugar levels and keeps them in a normal range. As blood sugar levels rise, the pancreas secretes more insulin.

Question 16

Glycogen

Answer 16

The storage form of glucose that is stored in the liver and muscles. It provides the body with a readily available source of energy if blood glucose levels decrease.

Question 17

Anaerobic activity

Answer 17

High intensity activity where your body needs for oxygen that it has (it’s need exceeds the supply)

Question 18

Collagen

Answer 18

The main structural protein in connective tissue. It’s mainly found in fibrous tissues such as tendons, ligaments, and skin.

Question 19

Nerve

Answer 19

Neurons bound together by connective tissue

Question 20

Fascia

Answer 20

Connective tissue fibers (primarily collagen) that forms sheets or bands to attach, stabilize, enclose, and separate muscles and internal organs

Question 21

Epimysium

Answer 21

The fascia that encases the entire muscle

Question 22

Endocrine system

Answer 22

Regulates the body through the production of hormones

Question 23

Principle endocrine glands

Answer 23

Pituitary, thyroid, parathyroids, adrenals, pancreas, gonads

Question 24

Afferent (sensory) division of the PNS

Answer 24

Carries nerve impulses from the skin, fasciae, joints, and visceral organs to the CNS (input)

Question 25

Efferent (motor) division of the PNS

Answer 25

Handles outgoing information. Two parts: somatic and automatic nervous systems

Question 26

Somatic nervous system

Answer 26

Conscious, carries nerve impulses from CNS to the skeletal muscles

Question 27

Automatic nervous system

Answer 27

Transmits impulses to the smooth muscles, cardiac muscle, and glands

Question 28

Mediastinum

Answer 28

The space that separates the lungs and contains the heart, aorta, esophagus, and part of the trachea

Question 29

Functions of the cardiovascular system

Answer 29

(Circulatory) distribute oxygen and nutrients to the cells, carry carbon dioxide and waste from the cells, maintain acid-base balance, and regulate body temp

Question 30

Superior vena cava

Answer 30

Carries deoxygenated blood from the upper half of the body to the hearts right atrium

Question 31

Sliding filament theory

Answer 31

How muscles contract when there is sufficient ATP (think actin, myosin pulling together and all the sacromerse shortening simultaneously)
