This study adds to the findings of previous experiments that support a potential effect of atrazine on the developing male reproductive system. In other studies, atrazine has been associated with demasculinized gonads and induction of hypospadias, a condition where the urethral opening is on the underside of the penis, in animal models (Agopian et al., 2013). Agopian’s study contradicts…

First, when stressed physically or mentally it messes with your whole-body system states “The American Institute of stress”. There are numerous emotional and physical disorders that have been linked to stress including depression, anxiety, heart attacks, stroke, hypertension, immune system disturbances that increase susceptibility to infections, a host of viral linked disorders ranging from the common cold and herpes to AIDS and certain…

Hormones operate using a type of mechanism. Releasing these hormones can trigger actions in particular target cells. One receptor on the cell membrane binds to one type of hormone. The binding hormones change the shape of the receptor, which causes the response to the hormone. Through the process of steroid hormone action, the hormone goes through a certain process of two steps. The hormone binds to receptors on the nuclear membrane once it is inside the cell that produces an…

SHORT ANSWER: Using the “Journey of the Sperm” illustration, 1) In the space below, correctly label each structure; 2) In the space below, describe the function of each structure (2.5 pts each) 1. Penile glans: The penile glans is the outermost tip of the penis and is very sensitive to physical stimulation. The glans consists of 4,000 nerves that allow it to be exceptionally sensitive. The female counterpart to the penile glans is the clitoris glans. 2. Vas deferens: The vas deferens allows for…

The regulation of acid and pepsin secretion is associated with a balance of chemo-transmitters delivered to the gastric mucosa by pathways that facilitate stimulation and inhibition. The physiologic stimulation of acid secretion is divided into the cephalic, gastric, and intestinal. The main component of gastric secretion is HCL which is a product of the parietal cells. The parietal cells are epithelial cells that secrete HCL and essential factors. Parietal cells are located in the gastric…

In the hypothalamus, there is a neural circuit known as the melanocortin system, which includes two populations of neuron located in the arcuate nucleus, that express the proopiomelanocortin propeptide (POMC) and agouti-related protein (AgRP) (Roseberry, Stuhrman et al. 2015). POMC propeptide is the precursor to the melanocyte-stimulating hormones (α, β, and γ-MSH) (Roseberry, Stuhrman et al. 2015). The melanocortin system plays a significant role in controlling feeding and body weight…

1. Explain the roles of hormones in sexual development. Hormones arouse cells and organs to specific activities and influence the way we look, feel, develop, and behave. 2. Describe the anatomy and physiology of the male and female reproductive systems. The visible part of the male sexual anatomy are the penis and the scrotum, the pouch that contains the testes. The testes makes testosterone and sperm. Immature sperm is stored in the epididymis. Inside the body are several structures involved…

Although the function of ICAM5 in the pituitary is unknown, its roles in the brain as a cell adhesion molecule have been extensively studied. ICAM5 is abundantly expressed in the dendritic filopodia and plays an important role in synapse formation with presynaptic axons, via the extracellular matrix molecule, vitronectin (63), and/or β1 integrins (32, 64). Once these connections are established, the extracellular domain of ICAM5 is cleaved, disrupting the cytoplasmic actin cytoskeleton through…

Hannah Len Mrs.Scribner Lcc Afternoon March 28 2017 Hannah Len Mrs. Scribner Lcc Afternoon March 28 2017 Hypopituitarism verses Hyperpituitarism Hypopituitarism is a rare disorder in both males and females where your pituitary gland has either failed to produce one or more of its hormones or isn’t producing enough. The pituitary gland is a small jelly bean shaped gland situated at the base of your brain, behind your nose and between your ears. While this is here it is…

family an endocrine disrupting substance that causes cancer? You would immediately throw it out and never buy it again. It would be a little hard to even figure that out if the labels are fibbed to hide ingredients from the buyer. Now what if you were spraying detergents or even putting on face products that had the same thing in both of them. It’s a little odd that detergents, what we clean our bathroom with and beauty products, what we put on our face could contain the same thing. Endocrine…
