Someone with damage to the hypothalamus cannot regulate their body temperature very well. This is because the hypothalamus is the _ in the homeostatic control of body temperature.
- A. control center
- B. effector
- C. receptor
- D. efferent pathway
Explanation
Explanation
The hypothalamus acts as the control center in the homeostatic regulation of body temperature. It detects changes in temperature and then triggers responses to maintain the body’s temperature within a narrow, optimal range. The effector organs (e.g., sweat glands, blood vessels) carry out the actions required to restore balance, but the hypothalamus is responsible for initiating and coordinating these responses.Correct Answer Is:
A. control centerWhich cranial nerve carries parasympathetic innervation to most of the body?
- A. Vagus (CN X)
- B. Trigeminal (CN V)
- C. Accessory (CN XI)
- D. Glossopharyngeal (CN IX)
Explanation
The vagus nerve (cranial nerve X) is the primary cranial nerve responsible for parasympathetic innervation to much of the body. It carries parasympathetic fibers to various organs, including the heart, lungs, and digestive system. It plays a key role in regulating autonomic functions such as heart rate, digestion, and respiratory rate, which are crucial for maintaining homeostasis.
Neurons are very metabolically active and require a steady supply of oxygen and glucose.
- A. False
- B. True
- C. Maybe
Explanation
Neurons are highly metabolically active cells that require a constant supply of oxygen and glucose. The brain, composed mainly of neurons, uses a large portion of the body’s energy to support neural activity, including transmitting electrical impulses. A lack of oxygen or glucose can lead to impaired brain function or damage to neurons.
If a bright light hits the retina, the iris constricts to limit the amount of light reaching the retina. This is an example of a:
- A. Negative feedback mechanism
- B. Positive feedback mechanism
- C. Abnormal response
- D. Myogenic response
Explanation
This is an example of a negative feedback mechanism. In this case, the bright light is the stimulus that causes the retina to send signals to the brain, which in turn triggers the iris to constrict, reducing the amount of light entering the eye. Negative feedback mechanisms work to counteract changes in the body and maintain homeostasis. In this case, the iris' response reduces the intensity of light reaching the retina, helping to prevent damage to the photoreceptor cells.
The space in a synapse between the pre-synaptic axon terminal and the post-synaptic dendrite is called the:
- A. Synaptic cleft
- B. Vesicle
- C. Myelin sheath gap
- D. Axon hillock
Explanation
The synaptic cleft is the small gap or space between the pre-synaptic terminal (at the end of an axon) and the post-synaptic dendrite or cell body of the next neuron. It is where neurotransmitters are released and bind to receptors, allowing for communication between neurons.
Nervous system cells which generate and propagate electrical impulses (action potentials) are known as:
- A. Neurons
- B. Microglia
- C. Schwann cells
- D. Oligodendrocytes
Explanation
Neurons are the primary cells of the nervous system responsible for generating and propagating electrical impulses, also known as action potentials. These impulses allow communication between different parts of the body and are essential for functions such as thought, sensation, and motor control.
Taste buds on the tongue and epiglottis contain:
- A. Gustatory receptors
- B. Stereocilia
- C. Photoreceptors
- D. Olfactory receptors
Explanation
Taste buds on the tongue and epiglottis contain gustatory receptors, which are specialized cells responsible for detecting taste stimuli. These receptors are activated by chemicals in food, such as sweet, salty, sour, bitter, and umami substances, which are then sent to the brain for processing, allowing us to perceive different tastes.
Which of the following would you expect to happen if the air temperature is 95°F?
- A. decreased secretion from sudoriferous glands
- B. vasodilation of blood vessels in the skin
- C. vasoconstriction of blood vessels in the skin
- D. shivering
Explanation
Explanation
In hot conditions, such as an air temperature of 95°F, the body works to cool itself down. Vasodilation occurs, which means the blood vessels in the skin expand, allowing more blood to flow near the surface. This helps release excess heat and cool the body. Additionally, sudoriferous (sweat) glands will increase secretion to promote evaporative cooling. Vasoconstriction and shivering are responses typically seen in cold environments.Correct Answer Is:
B. vasodilation of blood vessels in the skinThe three serous membranes in the body include the:
- A. epithelial and connective
- B. cardiac, pulmonary, and thoracic
- C. pericardium, pleura, and peritoneum
Explanation
Explanation
The three serous membranes are the pericardium (which surrounds the heart), the pleura (which surrounds the lungs), and the peritoneum (which lines the abdominal cavity and covers abdominal organs). These membranes secrete a serous fluid that reduces friction between the organs and their surrounding structures. The other options do not accurately represent the serous membranes.Correct Answer Is:
C. pericardium, pleura, and peritoneumThe somatic division of the peripheral nervous system controls:
- A. Involuntary motor functions
- B. Voluntary motor functions
- C. Visceral reflexes
Explanation
The somatic division of the peripheral nervous system is responsible for controlling voluntary motor functions. This includes the movement of skeletal muscles, which can be consciously controlled, such as walking, talking, and any other voluntary physical activities. The motor neurons of the somatic nervous system carry signals from the brain to the skeletal muscles.
