Quotes About Physiology

It's not in your eyes Your eyeballs won't change It's the muscles around your eyes

A stammering man is never a worthless one. Physiology can tell you why. It is an excess of sensibility to the presence of his fellow creature, that makes him stammer.

A stammering man is never a worthless one. Physiology can tell you why. It is an excess of delicacy, excess of sensibility to the presence of his fellow creature, that makes him stammer.

A cell can also look static under a microscope, yet its state is the product of more than a billion metabolic reactions every second.11 You are composed of at least thirty trillion cells, so in the last second your tranquil demeanour was sustained by an incomprehensible one hundred billion trillion reactions (1023, or 100,000,000,000,000,000,000,000). I'm now in my mid-fifties, so my wrinkles and aches and pains are the product of about 1032 reactions to date, roughly a billion times

We now know that free-radical signals are central to cell physiology, so we can begin to see why antioxidants (which mop up free radicals) do as much harm as good.

I am John's raging bile duct.

Too much estrogen, and you get bitch tits.

Here are some examples of long, over-stretched muscles at odds with short, tight muscles: rhomboids versus pectoralis major infraspinatus and teres minor versus subscapularis and pectoralis major superficial spinal muscles versus abdominal muscles hamstrings versus the rectus femoris triceps versus the biceps supinator versus pronator teres

His body and his mind went about their different businesses. The former, freed from conscious instruction, breathed, rolled, sweated, and digested. The latter went dreaming.

She'd read somewhere that normal, healthy men got up to twenty erections a day. Um...yep, Ares was definitely healthy.

In the frequent fits of anger to which the males especially are subject, the efforts of their inner feeling cause the fluids to flow more strongly towards that part of their head; in some there is hence deposited a secretion of horny matter, and in others of bony matter mixed with horny matter, which gives rise to solid protuberances: thus we have the origin of horns and antlers, with which the head of most of these animals is armed.

I looked up "skin" in the encyclopedia and confirmed that, sure enough, it is the human body's largest organ, a fact that suggests our surfaces are critical to who we are, not just the gateway to physical or spiritual depths but a profoundly important web of cells that, in protecting us, gives us form and function.

Female humans are the only primates with permanently enlarged buttocks. Enlarged female breasts evolved as a copy of the female posterior.

The fatigue produced on the muscles of the human frame does not altogether depend on the actual force employed in each effort, but partly on the frequency with which it is exerted.

Although rather rare, a person who has a preexisting narrow tubal lumen, such as the presence of acquired or congenital stenosis, may have severe discomfort on ascent, given the difficulty in passively opening the tube (i.e., higher opening pressures are required for the tube to open).

Let us still believe that the nerves proceed from the heart, and not from the brain, and that the heart is the seat of consciousness, and that the ring-finger is (as Aulus Gellius asserts) in the most direct communication with it!

The hypothalamus is one of the most important parts of the brain, involved in many kinds of motivation, among other functions. The hypothalamus controls the "Four F's": fighting, fleeing, feeding, and mating.

Men wake up aroused in the morning. We can't help it. We just wake up and we want you. And the women are thinking, "How can he want me the way I look in the morning?" It's because we can't see you. We have no blood anywhere near our optic nerve.

It takes seventeen muscles to smile and forty-three to frown.

WTFact: The human small intestine can reach up to eight meters in length. Why do you want to know that? Because all knowledge is important, f*ck-face.

An animal's ability to absorb oxygen is roughly proportional to the surface area of its lungs. Typical human lungs pack in a surface bigger than a tennis court. As an added complication, the labyrinth of windpipes must merge efficiently with the arteries and veins.

pulses of electricity, magnetism, sound, heat, vibration, and light that are transmitted to every part of the body via the circulatory system and extracellular fluids and thereby reach every cell in the body (see Figure 15.6). These signals may serve a variety of vital regulatory roles.

We have 200 trillion cells, and the outcome of each of them is almost 100 percent genetically determined. And that's what our experiment with the first synthetic genome proves, at least in the case of really simple bacteria. It's the interactions of all those separate genetic units that give us the physiology that we see.

Women are affected by lunar tides only once a month; men have raging hormones every day.
