"During labor, the brain triggers the release of oxytocin to continually stimulate contraction of the uterus until the baby is born" This is an example of:
-
A negative feedback mechanism
-
A positive feedback mechanism
-
There is not enough information
Correct Answer
A. A positive feedback mechanismExplanation
This statement describes a positive feedback mechanism. Positive feedback occurs when the output of a system amplifies or reinforces the initial stimulus, leading to a greater response. In this case, the brain triggers the release of oxytocin, which stimulates contractions of the uterus. As the contractions continue, more oxytocin is released, leading to stronger and more frequent contractions until the baby is born. This process demonstrates positive feedback because the initial stimulus (contractions) is amplified and reinforced by the release of oxytocin.Rate this question:

Brain
-
Heart
-
Diaphragm
-
Mediastinum
Correct Answer
A. BrainExplanation
The cranial cavity is a hollow space within the skull that houses and protects the brain. Just like the spinal cavity, which contains the spine, the cranial cavity serves as a protective enclosure for a vital organ. Therefore, the correct answer is brain.Rate this question:

Muscle is said to be ____________ to the skin.
-
Superficial
-
Lateral
-
Proximal
-
Deep
-
Medial
Correct Answer
A. DeepExplanation
Muscle is said to be deep to the skin because it is located underneath the layers of skin. The term "deep" refers to something being situated further inside or away from the surface. In the context of the human body, deep structures are typically located closer to the core or internal organs, while superficial structures are closer to the surface. Therefore, in relation to the skin, muscles are considered deep.Rate this question:

A body plane that divides the anterior and posterior portions of the body is called a frontal plane. The frontal plane is also known as the coronal plane. It is one of the three anatomical planes along with the sagittal and transverse planes. The frontal plane divides the body into front and back portions, perpendicular to the sagittal plane which divides the body into left and right portions.Rate this question:

The body is great at maintaining homeostasis through tempurature regulation. Which mechanism does temperature regulation follow?
-
A negative feedback mechanism
-
A positive feedback mechanism
-
There is not enough information
Correct Answer
A. A negative feedback mechanismExplanation
Temperature regulation follows a negative feedback mechanism. This means that when the body's temperature deviates from the set point, the body initiates processes to bring it back to the normal range. For example, if the body becomes too hot, the negative feedback mechanism will cause sweating to cool down the body. If the body becomes too cold, the negative feedback mechanism will cause shivering to generate heat and warm up the body. This continuous cycle of detecting and correcting temperature imbalances helps maintain homeostasis.Rate this question:

Example of a mechanism:
- Glucose from ingested food is absorbed in the intestinal wall and the level of glucose in blood rises.
- Elevation of glucose concentration in the blood then stimulates the pancreas to release insulin.
- As a result, blood glucose levels fall.
-
Glucose levels in blood fall
-
Glucose levels in blood rise
-
Pancreas releases insulin
-
Stimulation of the pancreas
-
Not enough information
Correct Answer
A. Glucose levels in blood riseExplanation
The initial stimulus in this mechanism is the rise in glucose levels in the blood. This increase in glucose concentration triggers a response in the pancreas to release insulin, which ultimately leads to a decrease in blood glucose levels.Rate this question:

Which correctly displays the pathway of communication with a negative feedback mechanism?
-
Stimulus -> effector -> receptor -> control center
-
Stimulus -> receptor -> control center -> effector
-
Stimulus -> receptor -> effector -> control center
-
Stimulus -> control center -> receptor -> effector
-
None of the above
Correct Answer
A. Stimulus -> receptor -> control center -> effectorExplanation
The correct answer is stimulus -> receptor -> control center -> effector. In a negative feedback mechanism, the pathway of communication starts with a stimulus, which is detected by a receptor. The receptor then sends signals to the control center, which processes the information and initiates a response. Finally, the control center sends signals to the effector, which carries out the response to counteract the original stimulus. This sequence of stimulus, receptor, control center, and effector represents the correct pathway of communication in a negative feedback mechanism.Rate this question:

-
Spinal cavity
Correct Answer
A. Pleural cavityExplanation
The correct answer is pleural cavity. The pleural cavity is the body cavity that contains the lungs. It is located within the thoracic cavity, which is surrounded by the rib cage. The pleural cavity is lined by a membrane called the pleura, which helps protect and lubricate the lungs during breathing.Rate this question:

Which of the following fits best? "The femoral region is ____________ to the crural region"
-
Inferior
-
Proximal
-
Lateral
-
Distal
-
Anterior
Correct Answer
A. ProximalExplanation
The femoral region is proximal to the crural region because the term "proximal" refers to a location that is closer to the point of attachment or origin. In this case, the femoral region is closer to the point of attachment (the hip) compared to the crural region, which is closer to the point of attachment (the knee).Rate this question:

Check all that apply: Which of the following organs can be found within the abdominopelvic cavity?
-
Heart
-
Bladder
-
Small intestine
-
Lungs
-
Ovaries
-
Testes
-
Spine
Correct Answer(s)
A. Bladder
A. Small intestine
A. Ovaries
A. TestesExplanation
The organs that can be found within the abdominopelvic cavity are the bladder, small intestine, ovaries, and testes. The bladder is a part of the urinary system, responsible for storing urine. The small intestine is a crucial organ in the digestive system, where the majority of nutrient absorption takes place. Ovaries are reproductive organs in females, responsible for producing eggs and hormones. Testes are reproductive organs in males, responsible for producing sperm and hormones. The heart, lungs, and spine are not located within the abdominopelvic cavity.Rate this question:

-
Distal; medial
Correct Answer
A. Lateral; distalExplanation
The brachial region is positioned both laterally and distally to the acromial region. This means that the brachial region is located further away from the midline of the body (lateral) and further away from the point of attachment (distal) compared to the acromial region.Rate this question:

In this example of a positive feedback mechanism, what is considered the effector?
-
Break in the blood vessels
-
Blood clots completed
-
Acceleration of clotting
-
The damaged cells
-
Bleeding
Correct Answer
A. The damaged cellsExplanation
In a positive feedback mechanism, the effector is the component that amplifies or enhances the initial stimulus. In this example, the damaged cells act as the effector because they trigger an acceleration of clotting, which in turn leads to the formation of blood clots. The blood clots are the amplified response to the initial stimulus of the break in the blood vessels, creating a positive feedback loop.Rate this question:
