Answer:
The two hormones, LH and FSH, are responsible for production of testosterone in boys. Testosterone is the male sex hormone produced in the testes. Blood levels of testosterone in boys rise during puberty, and this surge of hormone levels is responsible for development of the male features: facial hair, pubic hair and muscle development.
Explanation:
Answer: D. Begin assisting her ventilations with a bag-mask device and assess her pulse rate.
Explanation: In pediatric care
A Bag-valve-mask (BVM) device is a portable resuscitator. In pediatric care, when a patient is having trouble breathing, it is of utmost importance that the clinician first establishes an airway. A BVM with hundred percent oxygen should be used during the wait before intubation.
Once this has been done, the next priority is to monitor the pulse of the child. This can be through the done by a pulse oximeter or ensuring chest motions are synchronized with breathing sounds.
Answer:
Agonist muscles and antagonist muscles refer to muscles that cause or inhibit a movement.
Explanation:
Agonist muscles cause a movement to occur through their own activation.[4] For example, the triceps brachii contracts, producing a shortening contraction, during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while producing a lengthening contraction. It is still the agonist, because while resisting gravity during relaxing, the triceps brachii continues to be the prime mover, or controller, of the joint action. Agonists are also interchangeably referred to as "prime movers," since they are the muscles considered primarily responsible for generating or controlling a specific movement.
