Of the following nerves, which, if any, controls the Larynx during the process of breathing?
- A.
Phrenic
- B.
Intercostal
- C.
Vagus
- D.
None of the above
Correct Answer
C. VagusExplanation
The vagus nerve controls the larynx during the process of breathing. It is responsible for regulating the muscles that control the vocal cords and the opening and closing of the larynx. The vagus nerve plays a crucial role in coordinating the movements of the larynx during breathing, allowing for proper airflow and vocalization. The other options, phrenic and intercostal nerves, are involved in the mechanics of breathing but do not directly control the larynx. Therefore, the correct answer is Vagus.Rate this question:

In what part of the body is cerebral spinal fluid produced?
- A.
Ventricles of the Brain
- B.
Spinal Cord
- C.
Meninges
- D.
Medulla oblongata
Correct Answer
A. Ventricles of the BrainExplanation
Cerebral spinal fluid is produced in the ventricles of the brain. The ventricles are a system of interconnected cavities filled with cerebrospinal fluid that are located within the brain. These cavities produce and store the cerebral spinal fluid, which serves several important functions such as cushioning the brain and spinal cord, removing waste products, and providing nutrients to the central nervous system. Therefore, the ventricles of the brain are responsible for the production of cerebral spinal fluid.Rate this question:

Dilation of the pupil, a muscular response of the iris, normally occurs as a result of what?
- A.
Increased intensity of light
- B.
Decreased intensity of light
- C.
Irritation to the sclera
- D.
Irritation to the conjunctiva
Correct Answer
B. Decreased intensity of lightExplanation
The dilation of the pupil, a muscular response of the iris, normally occurs as a result of decreased intensity of light. When the amount of light entering the eye decreases, the pupil widens to allow more light to enter and improve visibility. This is a protective mechanism of the eye to adapt to different lighting conditions and ensure optimal vision.Rate this question:

What structure(s) of the inner ear provide(s) neural stimuli used to maintain equilibrium?
- A.
Fenestra rotunda
- B.
Fenestra ovalis
- C.
Semicircular canals
- D.
Organ of Corti
Correct Answer
C. Semicircular canalsExplanation
The semicircular canals in the inner ear provide neural stimuli used to maintain equilibrium. These canals are filled with fluid and are oriented in three different planes, allowing them to detect changes in head position and movement. When the head moves, the fluid in the canals also moves, which stimulates hair cells in the inner ear. These hair cells then send signals to the brain, which helps to maintain balance and coordination. The fenestra rotunda and fenestra ovalis are openings in the cochlea, and the organ of Corti is responsible for hearing, not equilibrium.Rate this question:

Absortion of food ocurrs prodominantly in which of the following areas of the intestines?
- A.
Duodenum
- B.
Jejunum
- C.
Ileum
- D.
Cecum
Correct Answer
C. IleumExplanation
The absorption of food occurs predominantly in the ileum. The ileum is the final section of the small intestine and is responsible for the absorption of nutrients, such as vitamins, minerals, and bile salts. It has a large surface area due to the presence of numerous tiny finger-like projections called villi, which increase the absorption capacity. The duodenum is the first section of the small intestine and is primarily responsible for the breakdown of food, while the jejunum is involved in further absorption. The cecum is the beginning of the large intestine and is mainly involved in the absorption of water and electrolytes.Rate this question:

The enzymatic action of amylaze results in the chemical breakdown of
- A.
Fats to fatty acids
- B.
Starches to fat
- C.
Starches to complex sugars
- D.
Proteins to complex sugars
Correct Answer
C. Starches to complex sugarsExplanation
Amylase is an enzyme that breaks down starches into simpler sugars. This process is known as hydrolysis, where water molecules are used to break the bonds between the sugar molecules in starch. As a result, complex starch molecules are broken down into smaller, more easily digestible sugar molecules, such as glucose and maltose. Therefore, the correct answer is "starches to complex sugars".Rate this question:

Correct Answer
C. Both 1 and 2 aboveExplanation
The correct answer is "both 1 and 2 above". This is because the concepts of health include both the absence of disease or disability and the soundness of mind, body, and spirit. These two aspects are often considered essential for overall well-being and a healthy lifestyle. The feeling of euphoria, on the other hand, is not necessarily a requirement for health and can vary from person to person.Rate this question:

In the immediate postoperative recovery phase, a patient's skin color may be indicative of all of the following EXCEPT
- A.
The patient's ability to recover from the anesthetic agent
- B.
Postoperative hemorrhage
- C.
Degradation of respiratory function
- D.
The development of shock
Correct Answer
A. The patient's ability to recover from the anesthetic agentExplanation
In the immediate postoperative recovery phase, a patient's skin color may be indicative of postoperative hemorrhage, degradation of respiratory function, or the development of shock. However, it is not indicative of the patient's ability to recover from the anesthetic agent. Skin color changes can be influenced by factors such as blood loss, oxygenation levels, and circulatory status, but not specifically by the patient's ability to metabolize or eliminate the anesthetic agent. Therefore, the patient's ability to recover from the anesthetic agent is not reflected in their skin color.Rate this question:

What source is considered the most frequent reservoir of infectious agents pathogenic to man?
- A.
Soil
- B.
Animals
- C.
Man
- D.
Plants
Correct Answer
C. ManExplanation
The correct answer is "Man" because humans are the most common source of infectious agents that can cause diseases in other humans. This is because humans can carry and transmit various pathogens through direct contact, respiratory droplets, bodily fluids, and other means of transmission. In crowded or unsanitary conditions, the risk of spreading infectious diseases among humans is significantly higher. Therefore, man is considered the most frequent reservoir of infectious agents pathogenic to man.Rate this question:
