There are not just five senses in a human body. A healthy human can sense its environment and its internal state through dozens of channels. Eyesight provides the most information to the brain per second and is the most important sense. The second most information-rich sense is hearing. Next up comes the sense of touch. But what is commonly called the sense of touch is actually a group of many independent senses including: hot, cold, pressure, pain, itching, and tingling.

Furthermore, there are actually three different types of pain senses: skin pain, joint pain, and organ pain. The sense of smell and taste are the other two common senses most people think of. The senses perhaps most valued by athletes are the senses of linear and angular accelerations, which are carried out by the inner ear

1. Smell is one of the senses that we often use when discussing sensory adaptation. Describe olfactory sensory adaptation. Why would it be important evolutionarily?

Sensory adaptation allows organisms to reach behavioral equilibrium with the ambient environment and respond primarily to changes in stimulation. Given its functional significance, it is not surprising that adaptation in the olfactory system exhibits many of the same characteristics as adaptation in other sensory systems, including vision. Repeated or prolonged exposure to an odorant typically leads to stimulus-specific decreases in olfactory sensitivity to that odorant, but sensitivity recovers over time in the absence of further exposure. Psychophysical analysis shows that olfactory adaptation results in elevations in odor thresholds and in reduced responsiveness to suprathreshold stimulation. Further, the magnitude of the decrease and the time course of adaptation and recovery are dependent on the concentration of the odor and on the duration of exposure. It is generally agreed that olfactory adaptation can occur at multiple levels in the olfactory system and can involve both peripheral (receptor level) and more central (post-receptor) components. Evidence for peripheral and central involvement comes from studies showing that monorhinal stimulation results in adaptation in both the ipsilateral and contralateral nostril, although the degree of adaptation in the ipsilateral nostril is more profound and recovery is slower.
This process is known as adaptation, and is a common feature in all sensorymodalities. Adaptation in olfactionallows the olfactory system to maintain equilibrium with the odorant concentrations in the ambient environment, yet respond appropriately to the appearance of novel odors or changes in odorant concentration.

What is Hashimoto Thyroiditis? How is it different than TSH

Hashimoto's thyroiditis is an autoimmune disease, a disorder in which the immune system turns against the body's own tissues. In people with Hashimoto's, the immune system attacks the thyroid.
Hashimoto's thyroiditis, the pituitary gland in the brain will make more TSH (your blood test for TSHcomes back high) because it thinks the thyroid is not making enough thyroidhormone.

Give two ways that you can tell anterior and posterior pituitary apart

The anterior pituitary receives signalling molecules from the hypothalamus, and in response, synthesizes and secretes seven hormones. The posterior pituitary does not produce any hormones of its own; instead, it stores and secretes two hormones made in the hypothalamus
