Pruitt lives in a city that is typically dominated by a maritime tropical air mass. After listening to the weather update, he le
kumpel [21]

Answer:

The correct answer is option C.

Explanation:

The masses of air move from the areas of high pressure to the areas of low pressure. Pruitt's city must be situated more or less within the equator for it to be dominated by maritime tropical air mass. This area gets adequate sunlight all throughout the year because of the comparative position of the Sun.  

Therefore, its atmosphere is usually more heated in comparison to that of the Polar Regions. The air in the tropic regions turns less dense and elevates into the upper atmosphere. The cooler and denser maritime polar air mass from the poles moves in to substitute the elevating air in the tropics, thus, developing incoming cooler winds.  

This is the reason for the creation of the trade winds across the globe and distributing energy around the planet to a more or less homeostatic level.

The sympathetic division of the autonomic nervous system prepares the body for stressful situations that require energy expendit
k0ka [10]

Answer:

True

Explanation:

The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by  via impulses transmitted through the sympathetic nervous system, and also secondarily  through catecholamines secreted from the adrenal medulla.

Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.

Thr route which convey impulses for sending, pain, temperature, touch and deep pressure are
anyanavicka [17]

Answer

The nervous system has many more sensory fibers and sensory pathways than motor fibers. This stems from the importance of properly understanding the environment prior to responding. These ascending tracts provide the bridge between the inputs from the environment and the organizing centers of the brain that provide the complexity of our responses. Somatosensory systems include the receptors and pathways for transmission of sensory information from the soma to the portions of the brain that need to integrate it and act upon it. While much of this is conscious, there are also ascending systems that convey unconscious information involved in coordination (proprioception) and brain stem reflexes.

There are several different modalities that fall under the broad topic of "exteroception". These sensations include well-localized touch 2-point discrimination), light touch, pain, temperature and vibration sense. These sensations can be tested clinically. Proprioception is the ability to detect the position of the body in space. This may be consciously perceived, such as with joint position sense, or it may be a sensation that is not perceived consciously, such as from muscles and ligaments.

Conscious sensation

We will first discuss the pathways for conscious perception before considering unconscious sensation. These pathways for conscious somatic sensation, at their simplest, require three neurons (and two relay sites) from the periphery all the way to termination the cerebral cortex. These steps are often described as first, second and third order neurons in the sensory pathway. The signal can be modified at each of the relay points (nuclei).
