autonomic nervous system

Answer: d. autonomic nervous system

Explanation:

The dilation of the pupil occurs due to the radial muscles. This is controlled by the autonomic nervous system. The autonomic nervous system consists of sympathetic and parasympathetic nervous system. The sympathetic nervous system controls the dilation of pupil whereas the parasympathetic nervous system controls the contraction of pupil.

A dilation response generally involves the widening of the pupil that may be caused by the adrenaline and drugs like cocaine, MDMA, amphetamines, hallucinogens and dissociatives.

A client receives a daily injection of glargine insulin at 7:00 a.m. when should the nurse monitor this client for a hypoglycemi
kherson [118]

This insulin has no peak action and does not cause a hypoglycemic reaction.

<h3>What is insulin?</h3>
  • Insulin is a peptide hormone generated by beta cells of the pancreatic islets and is encoded by the INS gene in humans.
  • Its name is derived from the Latin insula, which means "island." It is regarded as the body's primary anabolic hormone.
  • It promotes the uptake of glucose from the circulation into liver, fat, and skeletal muscle cells, which controls the metabolism of carbs, lipids, and protein.
  • The ingested glucose is transformed in these tissues into either glycogen (through glycogenesis) or fats (triglycerides), or, in the case of the liver, both, via lipogenesis.
<h3>What is the insulin's source?</h3>
  • The pancreas, an organ behind the stomach that produces the hormone insulin, is responsible for this.
  • The pancreas contains specific regions known as the islets of Langerhans (the term insulin comes from the Latin insula that means island).

How are dendrites synthesized in a neuron?
hram777 [196]

Answer:

The processing power of the mammalian brain is derived from the tremendous interconnectivity of its neurons. An individual neuron can have several thousand synaptic connections. While these associations yield computational power, it is the modification of these synapses that gives rise to the brain's capacity to learn, remember and even recover function after injury. Inter-connectivity and plasticity come at the price of increased complexity as small groups of synapses are strengthened and weakened independently of one another (Fig. 1). When one considers that new protein synthesis is required for the long-term maintenance of these changes, the delivery of new proteins to the synapses where they are needed poses an interesting problem (Fig. 1). Traditionally, it has been thought that the new proteins are synthesized in the cell body of the neuron and then shipped to where they are needed. Delivering proteins from the cell body to the modified synapses, but not the unmodified ones, is a difficult task. Recent studies suggest a simpler solution: dendrites themselves are capable of synthesizing proteins. Thus, proteins could be produced locally, at or near the synapses where they are needed. This is an elegant way to achieve the synapse specific delivery of newly synthesized proteins.

Question 15 (4 points)
algol13

Answer:

Standard <u>anatomical </u> position is the agreed-upon reference for body position when studying anatomy (option 2).

Explanation:

Anatomical position consists of the placement of the human body for its anatomical study, following certain norms established and accepted by convention.

  • <em>The body is observed from its front face. </em>
  • <em>The members must be extended, showing their ventral surface and with a slight separation from the rest of the body. </em>
  • <em>The hands show the palms, while the feet are hyperextended showing their backs. </em>

This position is useful to provide the description of any area of the body in a specific posture, and that can be understood even by those who do not observe.

The other options are not correct because:

<em>     1) </em><u><em>Histological</em></u><em>, refers to the study of cells and tissues. </em>

<em>     3) </em><u><em>Superior</em></u><em>, is a directional term, indicating something located at the top of the body or closer to the head. </em>

<em>     4) </em><u><em>Mnemonic</em></u><em> refers to the association of words used to remember names or lists of names.</em>

Explain why there is a difference in thickness of the walls​
lakkis [162]

<em><u>Answer:</u></em>

<em><u>Answer:The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. The left ventricle also has a thicker muscular wall than the right ventricle, as seen in the adjacent image</u></em>.
