What are Ears?

Well, your ear is a hearing organ with three parts: the outer, middle, and inner. 

  1. The outer ear is made of cartilage, a flexible tissue that forms the Pinna or auricle.

  2. In the canal there is the middle ear, called the tympanic cavity, which has three small bones that are connected and transmit the sound waves to the inner ear. The bones are called: Malleus, Incus, and the Stapes. These bones are not only the smallest in the human body but they use invisible sound waves to transmit sound through the inner ear to the brain. They do that because they are connected to a piece of tissue called the eardrum and it does exactly what it sounds like, the eardrum vibrates which, in turn, make all three bones vibrate and hit a nerve which sends the waves to the brain,

  3. The inner ear also consists of three parts but only one of these parts is for hearing, the Cochlea, this is the nerve we talked about that sends the waves to the brain. 

But what about the other two parts? Well, the other two parts are used for balance. That right, your inner ear controls your balance and the part that controls it is called the Vestibule and the Semicircular canals.

But how? Well the canals are filled with tiny hairs and liquid that move around when you move around. Think of it this way when you spin around the liquid in the canal is also spinning so you don’t fall down but when you stop abruptly your inner ear is still spinning, therefore, making you dizzy.

What happens when you crack your knuckles?

  What happens when you crack your knuckles? Well that popping sound is literally the action of tiny bubbles popping between your joints. In between your joints you have something called Synovial fluid, it kind of looks like an egg yolk. And when you stretch your joints, a gas is released and forms tiny little bubbles and when you compress or “crack” your knuckles you hear the popping of those bubbles. If I crack my knuckles will I get develop arthritis? A study conducted by Donald L. Unger where over the course of 60 years he cracked all his knuckles in his left hand and at the end of the time period he found out that he had the same amount of arthritis in his left as he had in his right, many other studies have been conducted and no negative medical effects have been reported, but one piece of advice... some people don't like to hear cracking your knuckles.

Common injuries when hiking and how to avoid them

Image
Hiking has and continues to be one of my favorite activities during the Covid shutdowns. Right now I have been focusing on hiking the PCT, Pacific Crest Trail! I have hiked around 50 miles of the total 2,650 miles, starting from the US/Mexico border and going north. In my hiking I have encountered a few injuries such as blisters and sore muscles and been trying to make sure I am prepared to prevent dehydration. Here are some tips and tricks on how to avoid or to be prepared if you get them.  Blisters First blisters, one way to avoid them is to have shoes that fit your feet well, if you do get blisters moleskin or duct tape is great to put on your feet and just to let your feet rest. Sore Muscles A few ways to avoid this is to eat bananas and to stretch before and after hiking. Also working out regularly before starting a long hike and taking an anti-inflammatory medication such as Tylenol before and after your hike. (You can cut the pill in half and do half before and the other ha...

The Human Hand

Image
  Few structures of human anatomy are as unique as the hand can be divided into several different categories that includes joints, ligaments, tendons, muscles, nerves, and blood vessels. Today we will talk about bones, tendons, and muscles.  Let's start with bones. The bones in your forearm are called the Ulna and Radius, those bones then connect to your wrist or Carpal bones, which connect to your Metacarpal bone of your palm and then your Phalanges or fingers. An interesting thing about the hand is that there are no muscles in your hand at all only tendons. The tendons in your hand connect to the muscles in your forearm, that is why when you wiggle your fingers your forearm moves because when the muscle flexes in your arm it pulls or releases the tendons and makes your finger move.
