Can a cymothoa exigua harm a human?

Little is known about the life cycle of Cymothoa exigua, since it is usually observed only when it has become a fish's prosthetic tongue. Other mouth-infesting crustacean females often mate while they are in the fish's mouth, using the sperm of males that live in the same fish's gills, so it is quite possible this is how Cymothoa exigua reproduce.

What does the axial skeleton consist of?

The skull marks the top of the axial skeleton, according to Rutgers University. The skull protects the brain from injury, It holds the eyes and ears and attaches to the mandible, or lower jawbone. In total, the skull consists of 28 different bones, including the small bones in the ear.\nThe vertebral column connects to the base of the skull. The vertebral column is comprised of 33 different bones, although several of these bones are fused together. For example, the sacrum is composed of five fused bones, according to the University of the Western Cape. The vertebrae protect the spinal cord and..

What is the difference between transudate and exudate?

Pleural effusion is an ailment caused by fluid collecting in the pleural space of the lungs and results in shortness of breath, chest pain and coughing. This ailment is often referred to as "water on the lungs."\nTransudate pleural effusion is a result of an imbalance in the production and removal of pleural fluid in the lungs. Diseases of the liver, kidneys or heart can all result in an imbalance filling pleural spaces with transudate. For instance, heart failure increases pressure in the small blood vessels responsible for removing pleural fluid, causing transudate to leak into the pleural s..

What are protons and neutrons called?

Protons and neutrons make up the nucleus of the atom, which is the densely packed center. The protons are positively charged while neutrons are neutral. Electrons are negatively charged, and they surround the nucleus in a series of shells. Atoms make up everything in the universe, from peaches to air to human beings. How many protons, neutrons and electrons an atom has determines what element it is, though on the periodic table of elements, the atomic number is based on the number of protons an element has.

What are the largest foot ligaments and tendons?

The plantar fascia runs from the heel to the toe along the sole of the foot and forms the arch of the foot, states the Arthritis Foundation. This ligament helps to balance the body and gives the foot enough strength to walk by stretching and contracting. The plantar fascia is designed to handle a large amount of stress, but it can become damaged through repetitive activity, obesity or tight muscles, according to WakeMed Health and Hospitals.

Where is the pituitary gland located?

The pituitary gland is an organ that is part of the endocrine system. It produces its own hormones and stores other types of hormones that control other gland systems throughout the body. The hormones found in the pituitary gland also control many bodily functions. The pituitary gland is divided into the anterior pituitary, the intermediate pituitary and the posterior pituitary. Each section of the pituitary produces its own specific hormones.

What are platelets?

Platelets form in the bone marrow when large cells called megakaryocytes fragment, releasing a thousand platelets per megakaryocyte, according to the University of Oklahoma Health Sciences Center. Surface proteins allow them to bind to blood vessel walls as well as to each other. Platelets also contain proteins that allow them to change shape and extend filaments to attach to a blood vessel wall or to other platelets. When platelets travel along the blood vessel wall and encounter an injury, they change shape to clump with each other onto the fibers of the broken blood vessel and prevent bleed..

Where can you find a lunar calendar?

As an alternative, a location sensitive lunar calendar can be found at Time and Date. The website detects the user's location automatically and offers a lunar calendar based on where the user is.\nPaul Carlisle offers simplified, .svg images of the phases of the moon. Images ini .svg format can be scaled up with no loss in quality.

What is the function of allelic ladder?

Researchers look at data from several hundred of people before constructing allelic ladders, which really show the most common alleles at each point. Alleles within specific places vary significantly from one person to the next. During testing, microvariants show up frequently, representing an incomplete repetition for an allele.\nWhen forensic scientists analyze samples, a 14-allele designation indicates that there are 14 matches on the fragment. A designation of 12.2 means there are 12 repeats and two additional bases. An allele represents the traits of one copy of a certain gene, or one cop..

What are characteristics of the Phylum Echinodermata?

Of all the phyla in the animal kingdom, the Phylum Echinodermata most closely resembles the Phylum Chordata, which includes humans. Echinoderms, like humans, have distinct spinal columns. They have coeloms deriving from digestive tubes, which resembles the internal digestive system of humans and many animals. Like people, organisms in the Phylum Echinodermata contain endoskeletons that form primarily from hard, dense calcium carbonate. Sharp spikes radiate out from the skeletons of echinoderms, giving them a distinct appearance.In addition to starfish, this phylum includes other aquatic specie..
