Mammary gland

(n.d.). Evaporation provides the major defense against overheating. The body’s surface contains approximately 2 million sweat glands. When the hypothalamus senses an increase in core temperature it will act by increasing blood flow to the skin, stimulating the sweat glands. The result is an increase in the rate of water loss through sweating which helps cool down (Vella, S, & Kravitz, n.d.). Physiology of Cardiovascular System Short-term: A physical…

A dry penis can also be itchy, flaky, uncomfortable and unattractive, and when normal epidermis lotions and moisturizers do not seem to help, it may be rough to know what to do next. Correctly, dry penis skin is most often the effect of private habits or external causes that have an effect on the body's level of hydration or sap the penile skin of its normal oils. Many of those issues can be addressed at home with the proper approach to penis care, serving to men to restrict disagreeable…

“Every living thing on the surface of the planet has a system to synchronize [itself] with day and night” (Barone 8). Sleep is a natural part of life and most people, at some point in their life, experiences difficulty sleeping. Today, however, sleep disruption is becoming a more prominent issue due to the rising number of electronic devices. Because of the blue light illuminance these devices produce, the brain’s secretion of the sleep-inducing chemical melatonin is disrupted; therefore,…

I froze in horror as I read the Facebook message that was sent to me. He’s gone. My heart fell to my gut. I felt a sharp pain down my spine. My head started throbbing- I wanted to throw up. My body trembled, and my hands turned to ice. I started looking around the room to make sure I wasn’t dreaming. I was trying to wake myself up from a nightmare that was my reality. According to Sapolsky, a neuroscientist of great renown, a “Stressor” is an event in the outside world that knocks you out of…

Introduction In vertebrates, reproduction is primarily controlled by the hypothalamus-pituitary-gonad axis. The gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus are key regulators of the hypothalamic neuroendocrine system mainly though the synthesis of GnRH (Moenter et al., 2003). The decapeptide GnRH is released from the hypothalamus in a pulsatile manner, and the amplitude and frequency of these pulses change throughout the estrous cycle (McCartney et al., 2002; Moenter et al.…

Hormone is a biological process that involves signaling molecules. These hormones “are secreted into extracellular fluid, which circulate in the blood or hemolymph of animals. This communicates regulatory messages throughout the body” (Reese 993). There are many things that may trigger a hormone to trigger different responses within the human body. This includes intracellular proteins and receptors. First, intracellular proteins act with intracellular receptors. “Intracellular receptors for…

The production of each hormone is kept balanced by the feedback mechanism between the individual gland (the thyroid, for example), the hypothalamus, and the pituitary gland. If a gland overproduces or underproduces a hormone, the master glands register this from the amount of hormone in the bloodstream. The master glands then respond by regulating the hormonal production. The system works with great precisior; despite the fact tat the hormones are transported in the bloodstream and are…

If there are any abnormalities to the natural release of the hormones within the human body that could negatively influence the human body in a variety of aspects at different stages of their life. Through the time period of a child becoming an adult they could experience poor growth to their height as well as their internal organs (You & Your Hormones, 2014). The lack of grow into adulthood could negatively influence their sense of well being, and increase their risk of heart disease and the…

Acne occurs in many pediatric adolescent patients. The initial cause of acne is a “clogged pore” which is keratin and sebum that rises to the surface of the skin. During puberty, androgens are released in the skin that elicits the glands to produce more sebum. The extra sebum mixes with the keratinocytes, plugs the pilosebaceous follicles to produce a “clogged pore” which is obstruction of comedones also known as blackheads and whiteheads (Ball, Bindler, & Cowen, 2015, P 1047). Open comedones…

every day to achieve the things that make you happy. Endorphins, serotonin, oxytocin and dopamine are released from the pituitary gland, which is located at the base of the brain. The pituitary gland is part of the endocrine system which is responsible for growth, reproduction, sleep, mood, etc. The pituitary gland is about the size of a pea and is known as the “master gland” since it controls many important functions in the body. Endorphins, also known as “feel-good” hormones, are associated…
