Viktor [21]

Answer:

The correct answer to the question: The pineal body secretes which hormone that maintains the body´s internal clock, the 24-hour wake-sleep cycle, and regulates the onset and duration of sleep?, would be, C: Melatonin.

Explanation:

The process of sleep and wakefulness, also called the circadian cycle, its a pretty complex system that is controlled by several parts of the brain, but most importantly, structures of the diencephalon (vital is the hypothalamus), the pineal gland, and the stem of the brain. All these structures, and some others, respond to changes both in light perception by the eyes and other senses, heat, and homeostatic balances. These factor play a vital role in telling the human body that it is time for sleep, or to awaken. The pineal gland, as part of this melody, is essential, as it secretes the hormone, melatonin, in response to light changes. Melatonin will balance out the process of sleep, when it is secreted in high quantities by the pineal gland, and wakefulness, when it is no longer secreted in response to the presence of light. This is what is called the circadian cycle.

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.

During a class on stroke, a junior nursing student asks what the clinical manifestations of stroke are. What would be the instru
skad [1K]

Clinical manifestations of stroke include severe headaches accompanied by vomiting and vertigo.

<h3>Clinical manifestations of stroke</h3>

The symptomatology depends on the location of the ischemic process, the size of the ischemic area, the nature and functions of the affected area and the availability of collateral flow.

The main sequelae resulting from a stroke are the neurological deficits that will be reflected throughout the body, unilaterally or bilaterally, as a result of the location and size of the brain injury, which may present as signs and symptoms of loss of voluntary control in relation to motor movements.  

With this information, we can conclude that the main symptoms of stroke are severe headache, nausea, and vomiting.
