The anatomical position is defined to be the body standing upright with face and torso and feet directed forward and arms around 45 degrees away from the torso with palms facing forward. This is a standard reference in human anatomy, especially in describing body part relations (i.e. the 5th digit of the hand is medial to the umbilicus, etc.). The ulna, in anatomical position is inside or medial to the midline of the body.
<em>An easy way in determining where the ulna and the radius are is that the ulna is in line with the pinky finger and the radius is in line with the thumb. </em>

<span>Having
constipation while also having hemorrhoids is a nightmare. You already face
inability passing out poop, yet you still have to brace for intense pain as you
strain to get it out. It is close enough to death by a thousand strains. In
those cases, doctors prescribe stool softeners so the patient can pass out
stools faster and experience lesser pain. Doctors have lots of laxatives to
choose from. The most common one prescribed for hemorrhoids-related
constipation is lactulose. Lactulose is composed of undigestible sugars that
swell once it travels down the large intestine, adding bulk to the stool. It is
preferred because it does not alter function of the intestines.</span>
Organisms in the domains of Archaea and Bacteria reproduce with binary fission. This form of asexual reproduction and cell division is also used by some organelles within eukaryotic organisms (e.g., mitochondria).
Answer:
<u> Neuromuscular Junction -</u> It is a chemical synapse formed by the contact between a motor neuron and a muscle fiber.
<u>Function- </u>As the motor neuron are <em>able to transmit the required signals</em> to the muscle fiber, which causes the muscle contraction.
Explanation:
<u>Steps in neuromuscular transmission:</u>
- calcium entry into the presynaptic terminus.
- diffusion of Ach across cleft.
- combination of Ach with post-synaptic receptors and Ach breakdown via esterase.
- opening of Na + /K + channels (cation channels).
- postsynaptic membrane depolarization (EPP).
