Thyroid glands are located in the neck, in close approximation to the first part of the trachea. In humans, the thyroid gland has a "butterfly" shape, with two lateral lobes that are connected by a narrow section called the isthmus. Most animals, however, have two separate glands on either side of the trachea. Thyroid glands are brownish-red in color.
Close examination of a thyroid gland will reveal one or more small, light-colored nodules on or protruding from its surface - these are parathyroid glands (meaning "beside the thyroid").
The microscopic structure of the thyroid is quite distinctive. Thyroid epithelial cells - the cells responsible for synthesis of thyroid hormones - are arranged in spheres called thyroid follicles. Follicles are filled with colloid, a proteinaceous depot of thyroid hormone precursor.
In addition to thyroid epithelial cells, the thyroid gland houses one other important endocrine cell. Nestled in spaces between thyroid follicles are parafollicular or C cells, which secrete the hormone calcitonin.
The structure of a parathyroid gland is distinctly different from a thyroid gland. The cells that synthesize and secrete parathyroid hormone are arranged in rather dense cords or nests around abundant capillaries.

Which digestive enzymes are produced by salivary glands?
In the oral cavityor the mouth, the salivary glands secrete ptyalin. It is a type of α-amylase, which acts upon starch and converts it into small segments of multiple sugars and into the individual soluble sugars.Salivary glands also secrete lysozyme, which kills bacteria but is not a digestive enzyme.some of the other minor enzymes secreted areBromelaine it acts on meat and acts as an anti-inflamatory agent.Betaine is linked with cell fluid balance as osmolytesSalivary Amylase (also known as ptyalin) (Mouth) produced by salivary glands breaks down starch into sugar.in short SALIVARY AMYLASE AND LYSOZYME
Are linked genes on the same chromosome?
Yes, linked genes are located on the same chromosome.
Genes that tend to be inherited together are said to be?
Linked On A Chromosome
When the trait is on the X-chromosomes what is it called?
When a trait is located on the X chromosome, it is referred to as an X-linked trait. This means the trait is inherited through the X chromosome and can show different patterns of inheritance compared to traits on autosomes. Examples of X-linked traits include red-green color blindness and hemophilia.
Are all sex-linked traits located on the X chromosome?
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
Is prostate cancer and thyroid problems linked?
No, there is no link.
Which describes an ethical dilemma related to food engineering?
Pesticides protect our crops, but some European countries have linked them to thyroid disorders.
Which type of gland is most linked to acne?
Oil glands are most linked to acne, which is why people with oily skin tends to have more acne, and this is also the reason you tend to have more acne in your "T-zone"
Can improper thyroid levels give false negative on pregnancy test?
Improper thyroid levels do not necessarily give a false negative on a pregnancy test. Improper thyroid levels, due to a thyroid condition, can affect a woman's ability to conceive or give birth to a healthy full-term baby. It's important for pregnant women with a thyroid condition to be monitored because these conditions can increase the chance for miscarriage, preterm delivery, gestational hypertension, eclampsia, and even decreased IQ in the baby.Related Article: HCG and the Thyroid: How Are They Linked?
Does the thyroid have anything to do with raynauds?
Raynauds occurs in autoimmune people when the nerves that control the blood supply to the hands and feet "misfire" and tell those blood vessels to close down. There are many thyroid diseases, some are autoimmune like Raynaud's. Frequently if a person has one autoimmune disease, they have others. However, thyroid and Raynaud's are not directly linked.
How are thyroid hormones stored?
They are stored in the colloid as the protein thyroglobulin. Thyroglobulin is essentially T3 and T4 linked together into a protein.
What types of cancer are linked to nuclear fallout?
Leukemia, thyroid cancer, nasal cancer, lung cancer, and prostate cancer (only in men, of course) are at the top of the list.

How can you die from thyroid cancer?
Most thyroid conditions are not life threatening. However, thyroid function is closely linked to heart function, and an excess of hormones suddenly released by the thyroid, or taken as thyroid supplements, can kill you.
What disease is linked to too many antibodies in the blood?
You have a anti immune problem. i have a anti immune disease because of gluten, which causes me to have hypothyroidism. because the gluten and thyroid hormone look similar. the antibodies keep adding up because they are trying to kill the gluten and sooner or later attack your thyroid and other tissues
Is thyrogine a amino acid?
i think you mean..thyrogen? Thyrogen is comprised of two non-covalently linked subunits, an alpha subunit of 92 amino acid residues containing two N-linked glycosylation sites and a beta subunit of 118 residues containing one N-linked glycosylation site. The amino acid sequence of thyrotropin alfa is identical to that of human pituitary thyroid stimulating hormone.
