Probably don't do any experiments that involve shoving reptiles in a sack and swinging them around your head, as someone will surely call the ASPCA on you. The type of dizziness that is associated with spinning around is called "vertigo". From wikipedia: Repetitive spinning, as in familiar childhood games, can induce short-lived vertigo by disrupting ...

Dizziness is caused by a continuing rotation of the fluids in the semi-circular canals of the vestibular system that transmit rotation information to the brain. After prolonged rotation of the body, the circular canal fluids are engaged in a rotating motion. This fluid motion continues even when the body has stopped moving. The persistent fluid rotation is ...

Gluten is a protein. The textbook answer is that protein is not stored in fat cells. Proteins are hydrolyzed into amino acids through digestion; some amino acids are ketogenic, and can contribute carbon towards fat biosynthesis. So some of the carbon that originates in gluten may be incorporated into a fatty acid. But the carbon has no 'memory' of its ...

Hand sweating has been fairly well-studied, both because sweating from the hands is one of the main mechanisms of heat dissipation at higher temperatures and because there is a significant effect on palmar sweating by the autonomic nervous system (the main cause of hyperhydrosis of the palms). Disregarding autonomic effects (stress response), the single ...

ATP is used (hydrolyzed) by ion pumps to transport ions such as calcium against their concentration gradient. Molecular motors (such as myosin and kinesin) also couple ATP hydrolysis with movement. However both these processes are separate and just because calcium flux changes happen during muscle contraction doesn't mean that it is the same ATP that ...

Does it mean that e-NOS and n-NOS are synthesized by mediation of Ca and calmodulin? Calmodulin is activated by binding to calcium and NOS is activated by binding to Ca2+-calmodulin. The binding changes the structural conformation which renders the enzyme active. See this. Are e-NOS and n-NOS expressed on macrophages after induction [...] ...

This paper, while mainly dealing with chronic nerve compression, appears to explain the effects of nerve compression on the blocking the transmission of neural impulses (causing the "sleeping limb" syndrome). This paper describes how the application of pressure on a nerve causes a miniature case of compartment syndrome, where the pressure causes the ...

Hraish is right about the relationship between emotions and gut-brain axis. Stress hormones released by the brain are responsible for the gut-brain reflexes. Anxiety is related to stress and stress hormones are released when anxiety is expressed by the individual. Irritable bowel syndrome(IBS) symptom-based diagnosis, which is having symptoms such as ...

It is very easy, use google + pathophysiology and read some articles in the actual topic. There are a lot of pathophysiology books as well (some of them pretty expensive). Another way to do an online course. Just a simple search about your example: It is known that AAAs are characterized by destruction of elastin and collagen in the media and ...

Paresthesia is defined as the abnormal sensation of the skin, such as numbness, tingling, pricking or burning. Paresthesia is a diverse medical condition and the definitions seems too vague. Most of the books define Paresthesia as a symptom of some other disease. Mostly Paresthesia is categorized as transient or permanent. Paresthesia can arise from several ...

Osmoregulation is a homeostasis regulation mechanism followed by salmons to adapt on both salt and fresh water. Osmoregulation is the active regulation of the osmotic pressure of an organism's fluids to maintain the homeostasis of the organism's water content; that is, it keeps the organism's fluids from becoming too diluted or too concentrated. Osmotic ...

Renin angiotensin is for regaining homeostasis. If you have lost salts, blood pressure and blood volume will decrease due to loss of fluids. But the renin angiotensin mechanism will try to undo this by stimulating uptake of Na+ and water. But still, they can not fully compensate for loss of Na+, INTAKE of Na+ is NECESSARY. By the way, the main stimulus for ...
