The structure responsible for preventing backflow of blood within the heart

What is valves?

100

This structure is known as the "voice box" and contains the vocal cords and epiglottis

What is the larynx?

100

This neuron structure carries electrical messages away from the cell body toward the terminal axons.

What is an axon?

100

These pancreatic hormones work together to regulate blood glucose.

What is insulin & glucagon?

100

This is the number of thoracic nerves in the body.

What is 12?
200

The type of blood vessel has walls only one cell thick to facilitate gas and nutrient exchange

What is capillaries?

200

The normal adult respiratory rate range

What is 12-20 bpm
200

These are areas of skin supplied by afferent (sensory) nerve fibers

What is a dermatome?

200

This hormone helps with muscle mass development.

What is testosterone?

200

According to the SCA Response Protocol, this is a common error that significantly reduces survival rates?

what is Delaying AED use to continue chest compressions 

300

This major artery supplies blood to the legs

What is femoral

300

This pleural injury presents with severe respiratory distress, distended neck veins, hypotension, and tracheal deviation toward the unaffected side?

What is tension pneumothorax

300

Afferent nerves are also known as ______ nerves because they carry signals ______ the CNS.

What is "sensory," and what is "towards"?

300

In the HPA axis stress response, this hormone is secreted by the adrenal cortex to mobilize fuel.

What is cortisol?

300

This a complex network of nerves (C5-T1) that provides motor and sensory innervation to the upper limb.

What is the brachial plexus?

400

An athlete collapses after being hit in the chest by a baseball. What is the most likely condition and the vital immediate response?

What is Commotio Cordis; immediate use of an AED

400

During inhalation, what happens to the diaphragm and thoracic pressure?

Diaphragm contracts and moves down; thoracic volume increases and pressure drops below atmospheric, drawing air in

400

A key clinical sign that indicates a spinal cord injury rather than a brachial plexus ("stinger") injury.

What is bilateral symptoms?

400
With this endocrine disorder, a person isn't able to metabolize energy effectively so they are gaining weight and fatigue quickly.

What is hypothyroidism?

400

 Draw and label the nerve impulse pathway from sense to response, beginning with a stimulus detected by a sensory receptor and ending with a muscle response. Label the afferent (sensory) neuron, the CNS integration point, and the efferent (motor) neuron, and indicate the direction of signal travel.

Stimulus detected by a sensory receptor → afferent (sensory) neuron carries the signal TOWARD the CNS → integration in the CNS (spinal cord/brain) → efferent (motor) neuron carries the signal AWAY from the CNS → effector (muscle) produces the response. Award credit for correctly labeling the afferent neuron, CNS integration point, and efferent neuron, and for arrows showing the direction of signal travel from receptor to muscle.

500

This cardiovascular condition is an inflammation of the heart muscle, often following a viral infection, and requires absolute rest

What is myocarditis

500

This test is considered the BEST way to check lung function

What is spirometry

500

 In Seddon's classification, this nerve injury is a complete severance of the nerve requiring early surgical intervention.

What is neurotmesis?

500

This endocrine-based condition does not improve with rest, only when the body is adequately fueled

What is RED-S?

500

Draw and label the circulation pathway of blood through the body, beginning with deoxygenated blood entering the heart from the body and ending with oxygenated blood returning to the heart from the lungs. List each chamber, major vessel, and indicate where gas exchange occurs. 

Deoxygenated blood returns from the body via the superior/inferior vena cava → right atrium → tricuspid valve → right ventricle → pulmonary valve → pulmonary arteries → lungs (gas exchange occurs in the capillaries surrounding the alveoli:  out,  in) → pulmonary veins → left atrium → mitral valve → left ventricle → aortic valve → aorta → systemic circulation to the body. Award credit for correct chamber sequence, correct vessel names, and correctly indicating gas exchange at the lungs/alveoli.
