Part--- one
How do we think?
What are thoughts? This question will
keep scientists, doctors and philosophers busy for decades to come. It all
depends how you want to define the term ‘thoughts’. Scientists may talk about
synapse formation, pattern recognition and cerebral activation in response to a
stimulus (seeing an apple and recognizing it). Philosophers, and also many
scientists, will argue that a network of neurons cannot possibly explain the
many thousands of thoughts and emotions that we must deal with. A sports doctor
might state that when you choose to run, you activate a series of well-trodden
pathways that lead from your brain to your muscles in less than just a second.
There are some specifics we do know though – such as which areas of your brain
are responsible for various types of thoughts and decisions.
Why do we fiddle subconsciously? I’m constantly playing with my hair
This is a behavioral response some
people play with their hair when they’re nervous or bored. For the vast
majority of people such traits are perfectly normal. If they begin to interfere
with your life, behavioral psychologists can help but it’s extremely rare that
you’ll end up there.
What is a pulse?
When you feel your
When you feel your own pulse, you’re
actually feeling the direct transmission of your heartbeat down your artery.
You can only feel a pulse where you can compress an artery against a bone, e.g.
the radial artery at the wrist. The carotid artery can be felt against the
vertebral body, but beware, if press too hard and you can actually faint, press
both at the same time and you’ll cut off the blood to your brain and, as a
protective mechanism, you’ll definitely faint!
Why can some people roll their tongues but others can’t?
funny questions with answers/funny questions/funny questions to ask/tricky questions and answers/amazing answers to curious questions
Although we’re often taught in school that tongue rolling is due to genes, the truth is likely to be more complex. There is likely to be an overlap of genetic factors and environmental influence. Studies on families and twins have shown that ft simply cannot be a case of just genetic Inheritance. Ask around - the fact that some people can learn to do it suggests that in at least some people It’s environmental (lea learned behavior) rather than genetic (inborn).
Do eyeballs grow like the rest of the body?
Only a
small amount his is actually why babies appear to be so beautiful, as their
eyes are out of proportion and so appear bigger.
In the mornings, do we wake up or open our eyes first?
Sleep is a
gift from nature, which is more complex than you think. There are five stages
of sleep which represent the increasing depths of sleep when you’re suddenly
wide awake and your eyes spring open, it’s often a natural awakening and you’re
coming out of rapid eye movement (REM) sleep; you may well remember your
dreams. If you are coming out of a different phase. E.g. when your alarm clock
goes off, it will take longer and you might not want to open your eyes straight
away!
What’s my field of vision in
degrees?
funny questions with answers/funny questions/funny questions to ask/tricky questions and answers/amazing answers to curious questions
The human
field of vision is just about 180 degrees. The central portion of this
(approximately 120 degrees) is binocular or stereoscopic i.e. both eyes
contribute, allowing depth perception so that we can see in 3D. The peripheral
edges are monocular, meaning that there is no overlap from the other eye so we
see in 2D.
How fast does blood travel round the human body?
Your total
‘circulating volume’ is about five liters. Each red blood cell within this has
to go from your heart. Down the motorway-like arteries, through the back-road
capillary system, and then back through the rush-hour veins to get back to your
heart. The process typically takes about a minute. When you’re in a rush and
your heart rate shoots up. The time reduces as the blood diverts from the
less-Important structures (e.g. large bowel) to the more essential (e.g.
muscles).
Why do we burp?
A burp is
the bodies’ way of releasing gas naturally from your stomach. This gas has
either been swallowed or is the result of something that you have ingested—such
as a sparkling drink. The sound is vibrations which are taking place in the
oesophageal sphincter, the narrowest part of the gastrointestinal tract.
What is the point of tonsils?
The tonsils
are collections of lymphatic tissues which are thought to help fight off
pathogens from the upper respiratory tract. However, the tonsils themselves can
sometimes even become infected leading to tonsillitis. The ones you can see at
the back of your throat are just part of the ring of tonsils. You won’t miss
them if they’re taken out for recurrent infections as the rest of your immune
system will compensate.
What are lips for?
Lips are predominantly used as a
tactile sensory organ, typically for eating. But also for pleasure when
kissing. They are also used to help fine-tune our voices when we speak.
Why does it feel so weird when you hit your funny bone?
You’re actually hitting the ulnar
nerve as it wraps around the bony prominence of the ‘humerus’ bone, leading to
a ‘funny’ sensation. Although not so funny as the brain interprets this sudden
trauma as pain to your forearm and fingers!
How many inches of hair does the average person grow from their head each year?
It’s different for everybody your
age, nutrition; health status, genes and gender all play a role. In terms of
length, anywhere between o.5 to 1 inch (12-2.5cm) a month might tends to be
considered average, but don’t be surprised if you’re outside this range.
Why do we blink?
Blinking helps keep your eyes clean
and moist. Blinking spreads secretions from the tear glands (lacrimal fluids)
over the surface of the eyeball, keeping it moist and also sweeping away small
particles such as dust.
Why do amputees sometimes still feel pain in their amputated limbs?
This is ‘phantom limb pain’ and can
range from a mild annoyance to a debilitating pain. The brain can sometimes
struggle to adjust to the loss of a limb, and it can still ‘Interpret the limb
as being there. Since the nerves have been cute it interprets these new signals
as pain. There isn't a surgical cure as yet, though time and special
medications can help lessen the pain.
