A) Growth plate and Endochondral ossification: In order to maintain a healthy skeletal system which is crucial for different organs such as respiratory system‚ brain‚ spinal cord and heart‚ it is very important to have a good development of the skeletal system. Endochondral ossification is the process through which the axial and appendicular skeletons are formed through the formation of a cartilage inter-mediate. A good model for endochondral ossification is the limb bud where the precursor cells

Hypothyroidism Normally‚ the thyroid-stimulating hormone (TSH) is produced when the hypothalamus excretes thyrotropin-releasing hormone (TRH). The secretion of TRH triggers the pituitary gland to release TSH. TSH then activates a release of triiodothyronine (T3) and thyroxine (T4)‚ controlling the body’s metabolism. When T3 and T4 levels rise‚ the secretion of TRH and TSH decrease. When thyroid hormone levels decline‚ there is an increase in TRH and TSH secretion (Buttaro‚ Trybulski‚ Bailey‚ & Sandberg-Cook

which act as “chemical messengers” in an effort to regulate particular bodily functions such as metabolism and growth. These hormones are produced by the pancreas‚ thyroid‚ pituitary‚ pineal‚ and adrenal glands which are also referred to as the endocrine system. Hormones are additionally produced in the ovaries in women and the testes in men. The secretions of particular hormones assist the body in maintaining a state of balance or homeostasis. When one or more hormones within the body are produced

Body Systems There are 10 body systems‚ one of them is the Integumentary (skin). It is composed of hair‚ skin‚ nails‚ sense receptions and oil glands. Its functionis to protect from outside‚ to regulate the body temperature‚ to make synthesis of hormones & chemicals and is used as a sense organ. Another one is the Skeletal System (bones). It is made of about 206 bones‚ that are divided in tho categories: axial bones (in the body by itself) and apendicular bones (arms & legs). We have Joints too

Adrenal gland In mammals‚ the adrenal glands (also known as suprarenal glands) are the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones in conjunction with stress through the synthesis of corticosteroids and catecholamines‚ including cortisol and adrenaline (epinephrine)‚ respectively. Anatomy and function Anatomically‚ the adrenal glands are located in the retroperitoneum situated atop the kidneys‚ one on each side. They are

Above the kidneys are two yellowish- orange colored glands that are approximately two and half by one inch called the adrenal glands. The adrenal glands play a very important role in secreting hormones and protecting the body from stress. The adrenal glands are composed of two parts‚ the adrenal cortex and the adrenal medulla. The adrenal cortex is the outer part of the adrenal gland that produces steroid hormones that regulate many different body functions. Not only that‚ but a hormone called aldosterone

Normal Thyroid Essay The thyroid is located in the neck superior to the thyroid cartilage‚ also known as the “Adam’s apple”. It has two lobes which are joined by an isthmus. The thyroid gland has a sufficient blood supply which consists of four arteries to ensure adequate blood flow‚ thyroid bruit with enlargement‚ and “C” cells interspersed with follicular cells. The Superior thyroid artery branches off the common carotid artery and the inferior thyroid artery which branches off the Subclavian

Gonadal sex hormones are produced by gonadotropins (FSH- Follicle Stimulating Hormone and LH- Luteinizing hormone) from the anterior pituitary gland located at the base of the brain. They stimulate male and female gonads to produce hormones of their own. FSH and LH secretion is controlled by GnRH (gonadotropin-releasing hormone)‚ which is a releasing hormone from the hypothalamus. The sex of an embryo is determined at fertilization‚ but secondary sex characteristics develop at puberty. Testosterone
