Sweat gland

Animals are multicellular, eukaryotic, heterotrophic organisms who use various systems of control to maintain homeostasis, the stable internal equilibrium that is brought by certain physiological processes. When a stable internal environment changes, it is the responsibility of the animal’s body to bring conditions back to equilibrium. Animals maintain homeostasis to survive successfully; homeostasis is maintained by feedback systems within the body. These feedback systems regulate aspects of…

Integumentary system is the organ system that protects the body from damage. The system includes skin, nails, skin derivatives hair and glands. The integument is the largest system of the body. It includes 16% of our body weight. It is made up of two parts cutaneous membrane and accessory structures. The accessory structures include hair, nails and exocrine glands. Cutaneous membrane is the epidermis and papillary layer of the dermis. The papillary layer is the uppermost layer of the skin.…

eyes, ears and mouth are formed. The digestive and urinary systems start functioning as well. The first sign that the mother may experience is a missed period. The embryo’s limbs grow to form webbed feet and hands and the thyroid, adrenal glands and pituitary glands have fully formed and their eyes are now open. At week 8 a diagnostic ultrasound scan can be offered to the mother. At 12 weeks the embryo is now known as a foetus and all the organs and muscles are fully formed. The sex of the…

Parkinson's disease is a long-lasting disease that affects all parts of the body. This disease is a chronic neurodegenerative disease that has no cure, but a lot of symptoms. This disease was first described by a British doctor named James Parkinson’s in 1817 and was first called as shaking palsy. Parkinson’s disease has been around for a very long time and dates to around 5000 B.C. There are different conditions and problems that are like Parkinson’s disease like Essential tremor, Lewy-body…

about a very important hormone called ADH shorten for Antidiuretic hormone and also known as vasopressin. Antidiuretic hormone is made in an area at the base of the brain known as the hypothalamus, the hormone is transported to the posterior pituitary glands where the hormone is released into the bloodstream. They carried around the body in your blood to their target organ, in this case, the Kidney to control what is been changed in your body. The main role of ADH hormone is to control how your…

Choice “C” is the best answer. Hidradenitis suppurativa (HS) is a chronic disease that entails painful, inflamed lesions in the axillary, inguinal, and anogenital areas, where apocrine sweat glands are present. Biopsy is rarely required, especially in well-developed lesions. Diagnosis of HS is clinical, and is based on the presence of typical lesions in a characteristic distribution, with recurrence (one accepted criterion is two recurrences over a period of 6 months)[1]. Choice “A” is not the…

A vital tenet of forensic science is the exchange principle first proposed by Edmund Locard, which can be generally understood as the phrase “with contact between two items, there will be an exchange.” Every time there is a contact between individuals, environs and articles, there is an exchange of physical evidence, however small it may be. This aspect plays an indispensable role in crime scene investigations as it enables the detectives to establish links between the crime scenes, victims and…

hair follicles, oil (sebaceous) glands and sweat (sudoriferous) glands. Sebaceous glands secrete greasy substances called sebum that will moistens the hair, waterproofs the skin as well as inhibit growth of some bacteria. During childhood, sebaceous glands are relatively small and inactive. However, during puberty, androgen hormones from the testes, ovaries and adrenal glands will stimulates the activation of sebaceous glands, therefore increases the size of the glands as well as the production…

I pick the integumentary system. The organs with this system are skin, hair, nails, and oil glands. The skin is the body’s outer covering and forms a barrier to protect the body from chemicals, disease, and physical change. Hair and nails protect it from infections. The oil glands produce sweat and moisturize the skin. This elps with dehydration and regulate body temperature, and throws away waste. A few possible ailments are *acne* where the skin on the body become clogged and look like…

body’s senses detect this temperature change, sends a signal through the afferent pathway to the integration center(brain). The integration center sends a signal via the efferent pathway to the effectors. In Mark’s case, the effectors were his sweat glands, opening up to cool the temperature and the blood rushing to the skin to also try to cool him off. 2. Mark’s low blood pressure can be explained by the fluid loss by sweating. Since Mark was not able to rehydrate the fluids he lost, the…
