Major Differences Between Endocrine And Exocrine Glands Essay

12. Both the nervous system and the endocrine system are used to convey messages throughout the body and coordinate organs, systems, and behavior. Compare and contrast how these two systems function.

1. Identify the major endocrine glands and other organs containing endocrine cells on models and diagrams (glands listed below).

5. What is the difference between apocrine, merocrine and holocrine glands? Which is the most common?

Adrenaline is hormone that is secreted by your adrenal

Learning Objective 2: 18.6.2 Describe the location, histology, hormones, and functions of the anterior and posterior pituitary.

An organ that can be classified as both an endocrine and exocrine gland is the

The adrenal glands are composed of two sections, the medulla and the cortex. The medulla part of the gland is what produces adrenaline-like hormones. The cortex produces a group of hormones called corticosteroids

Hormone cells are typically of a particular cell type, residing within a certain endocrine gland, such as thyroid gland, ovaries, and testes. Hormones exit their cell of origin through the process of exocytosis

The pituitary is stimulated to release growth hormone (GH) by growth hromone releasing hormone (GHRH) produced in the hypothalamus. It is inhibited from releasing growth hormone by growth hormone release-inhibiting hormone(GHRIH), also produced by the hypothalamus.

According to Shier, Butler & Lewis (2009) “other glands that produce hormones and thus are parts of the endocrine system include the pineal gland and the thymus gland”. Shier et al., 2009 argued the pineal gland, located deep between the cerebral hemispheres, secretes hormone melatonin that acts on certain brain regions that function as a biological clock. The changing levels of melatonin across 24 hours enable the body to know when day is and when is night.

Exocrine gland release substances through ducts or tubes that lead the external surface of the membrane, sweat glands, saliva, or the gastrointestinal tract. Endocrine gland doesn’t have any duct that lead to the surface, it diffuses its secretion into the bloodstream.

Gonadotropin is released from the hypothalamus. It travels through the hyposeal tract into the anterior pituitary lobe. The anterior pituitary lobe is stimulated by gonadotropin to release follicle-stimulating hormones (FSH) and lutenising hormones (LH) into the blood to stimulate the gonads to produce sex steroids such as testosterone. Growth hormones also operate using this mechanism.

Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use by body cells.

The Pituitary Gland - The pituitary gland is a pea-sized structure located at the base of the brain, just below the hypothalamus, to which it is attached via nerve fibers. It is part of the endocrine system and produces critical hormones, which are chemical substances that control various bodily

Adrenal glands, located near the kidneys, secrete several hormones that are activated by the nervous system. These hormones dictate the body’s reaction to stressful situations. Each person secretes a different amount of hormones, therefore affecting behavior in stressful situations differently (Morris & Maisto, 2005).
