After receiving information on various forms of birth control, a young couple decides to use a barrier method because they would

like to try and conceive in a year or two. Which barrier method uses a rubber barrier to hold spermicide against the cervix?

Answer:

The correct answer is diaphragm.

Explanation:

One of the barrier methods of controlling birth is the diaphragm. It is abstemiously efficient, with a one-year failure rate of approximately 12 percent with the typical application. It is positioned over the cervix with spermicide prior to having sex and is left in position for about 6 hours post-sex.  

It is a rubber barrier that holds the spermicide against the cervix. The spring in the diaphragm's rim produces a seal against the walls of the vagina. The diaphragm covers the cervix and physically inhibits sperm from getting inside the uterus via the internal orifice of the uterus. Basically, the diaphragm has an application with spermicide, and it is broadly considered that the spermicide substantially enhances the efficacy of the diaphragm.

Stells [14]

Answer:

The effector organ is affected by the fourth structure of the reflex arc.

Explanation:

When talking about the reflex arc, we refer to the sequence of events that occur for the body to react to an external stimulus.

In general terms, the peripheric nervous system receives information from a stimulus coming from the external environment. This information is sent to the central nervous system, where it is processed. From the CNS, another signal is sent as a response to the stimulus. This mechanism is known as the reflex arc.

Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.

There are three types of neurons involved in the mechanism:

• Afferent or sensorial neurons

• Interneurons

• Efferent or motor neurons

Action:

  • Ascending branch

The stimulus reaches the body and is received by the specialized sensory <u>receptors</u>. Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy. <u>Afferent neurons</u>, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.

  • Descending branch

Once the information reaches the central nervous system, it is processed by the<u> interneurons</u> that analyze it before sending a response. Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.

<u>Efferent neurons</u> receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the <u>effector organs</u>. The effector organ can be a muscle or a gland.

Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.

Can someone answer this please?
gulaghasi [49]

Answer:

"Fat cell, yellow bone marrow, femur, nervous system."

Explanation:

Via process of elimination, we can eliminate the first and last answers, as the biggest unit of a single organ system would be the entirety of the system, and those have the system itself jumbled in between the list.

That leaves us with the center-two answers. I believe "bone" is too vague, meaning that bone, in some cases, may be smaller than cartilage, thus, leaving you with the above answer.
