Exercise 1: The Endocrine System

3. Associated with the hair follicles are holocrine glands called __SEBACEOUS___, which produce a skin oil called ___SEBUM_______.

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

To continue, I then began to examine the endocrine system of the fetal pig. I began this dissection by finding the endocrine organs that are located in the area of throat. These organs were the thyroid and thymus. The thyroid’s responsibility is to produce amino acids that will help to regulate metabolism. The shape of the thyroid is oval like, and has a dark brown tint. The second endocrine organ found in the throat is the thymus. The thymus functions to provide immunity against diseases. It has a pink appearance, and is long in length. I was successful in finding three endocrine organs in the abdominal cavity. The first organ found was the adrenal gland. The function of this gland is to produce various hormones. This gland is identifiable

1. How does the urinary system relate to sexual function in males? How does the prostate relate to the bladder infections in males?

Figure 2: The figure below illustrates how the interior structure of the pituitary gland and hypothalamus facilitate for hormone secretion. The pituitary gland consists of the posterior and anterior lobe. It is lined with

The tropic hormone stimulates an endocrine gland to grow and secrete it’s hormones. They are secreted by the adenohypophysis (anterior pituitary gland) (Taylor, 2016). Examples are FSH-follicle stimulating hormones which help the female ovaries to mature and to ovulate. Adrenocorticotropic hormone (ACTH) stimulates the adrenal cortex and secretes cortisol (Taylor, 2016).

No late Pre-Lab assignments will be accepted. Questions 1. What are the two molecules you will separate in this laboratory exercise?

The classic endocrine glands include the pituitary, thyroid, parathyroid, pancreatic islets, adrenals, and gonads (ovaries and testes). The thyroid is the largest of the classic endocrine glands (1). It is a butterfly-shaped gland positioned anterior of the trachea. Consisting of two lobes connected by a band of connective tissue called the isthmus. Each of the lobes is approximately 4 cm x 2 cm, and in an average adult, weigh about 20g.

Using Figure 9.2 (page 226) from Holes, Human Anatomy and Physiology be able to identify the lobes in the brain. Be able to describe the function of each lobe.

There are two parts to the pituitary gland, the anterior pituitary and the posterior pituitary.  The anterior pituitary has two types of chromophils, acidophilus and basophils.  These two are separated into different classes of cells that have differing secretory products and aim for different organs.  The anterior pituitary discharges five different types of hormone, somatotrophs, mammotrophs, corticotrophs, tyrotrophs, and gonadotrophs.  The posterior pituitary only releases two hormones, antidiuretic

This is a nice overview of the female functions. The primary sex characteristics is what make the male different from the female, and the female different from the male. Gonads are the sex glands, the ovaries in the female and for the male it is the testicles. The ovaries in the female is what secrets progesterone, and the testes in the male secrets testosterone. In the female progesterone is what helps develop the body’s secretory portions of the breast and it help with maintaining pregnancy. In the male testosterone is what helps them develop their body hair, deep voice and muscular shape.

Figure 5: the location of the pituitary gland (upper left) and its anatomy (upper right). The middle is a schematic drawing of the pituitary and the lower (from left to right) are: histology of the anterior pituitary, the pituitary histology, pars nervosa and distals and at far right is a section in the posterior pituitary.

*Each kidney is divided into three lobes. *Each lobe is divided into many lobules. *A small, elongated and yellowish adrenal gland is present attached to the anterior lobe of each kidney. *Each kidney is composed of a large number of nephrons

In response to task 1 I have created a table illustrating each of the 10 body systems and their main anatomical features. I will also be identifying the main functions of the following three systems:
