Endocrine gland

to have quick speed and agility. The cardiovascular and circulatory system of a dog pushes the blood around the body with oxygen and nutrients for the cells and removes waste. “This includes a four chambered heart, arteries, veins, and lymphatic glands and vessels” (“Canine Physiology”). The circulation of blood provides the dog's body with oxygen and removes carbon dioxide from it. Oxygenated blood and deoxygenated blood circulate…

regulated by two systems, the nervous system and the endocrine system. These systems are responsible for initiating the ‘flight or fight’ response in the body. The sympathetic nervous system and the parasympathetic nervous system form the autonomic nervous system, which aids in the control of most unconscious actions of the body, including heart rate, digestion and salivation. Stress primarily acts by activating the sympathetic nervous system. The endocrine system is a collection of…

senses, (smell, touch, see, taste, and hear.) http://study.com/academy/lesson/sensory-neurons-definition-function-quiz.html A motor neuron does the complete opposite of the sensory neurons. A motor neuron signal goes from your brain to your muscles or glands, example is your motor neurons tell your hand to open a door to walk out. http://www.gwinnett.k12.ga.us/LilburnES/PromoteGA/biochemistry/Neurons_types.html An interneuron is what connects neurons in the spinal cord and brain so they can…

Introduction Graves' disease, or toxic diffuse goiter, is an autoimmune disease where too much activity of the thyroid gland causes an overproduction of thyroid hormones such as T3 and T4. The disease is known for resulting in hyperthyroidism (an over active thyroid) which causes an enlarged thyroid and eye problems among other things. A large amount of different conditions and effectors can cause hyperthyroidism, but Graves' disease has shown to be one of the two most common. The disease can…

by a minion, the nerve endings underneath his skin pick up the stimulus and a process begins. Next, an impulse in sent towards the brain telling it what happened. The impulse travels through axons, which connect cell bodies to muscles, neurons, or glands. This process occurs over and over, and is sped up by the use of the myelin sheath. The myelin sheath speeds up the movement of neural impulses in an axon by covering it in a layer of fatty tissue. This is necessary due to the fact that some…

Homeostasis is the action of maintaining a healthy internal environment. One example of homeostasis that we did in class is when we walked in place, causing our heart rate and breathing rate to increase while exercising to maintain a constant supply of oxygen. Another example from our reading is that sweating helps to maintain homeostasis by removing excess salt and opening pores to cool you down. It is important for organisms to maintain homeostasis because it assists the cells in the body to…

The thyroid gland is responsible for production of two hormones: thyroxine (T4) and triiodothyronine (T3) (1). This patient is presenting with this array of symptoms as a result of a severe form of hypothyroidism called myxedema coma (2). Thyroid hormone affects many tissues in the body, and is responsible for body functions such as metabolism of fat, protein and glucose for energy and heat production (1). Thus, it can be concluded that the patient is experiencing constipation, hypothermia and…

1. Distinguish between afferent and efferent nerves. Afferent nerves are the sensory nerves. They carry information from the world to the brain and spinal cord. Efferent nerves are the motor nerves they carry information out of the brain and spinal cord to other parts of the body. Afferent nerves take in information and efferent nerves carry out information. 2. Study Figure 2.1. What makes up the Central Nervous System (CNS)? The central nervous system is made up of the brain and…

Cystic Fibrosis What is Cystic Fibrosis? Cystic Fibrosis is a genetic disease that is one of the most common and lethal. The disease is usually noticeable in the victim by the age of 3 and impairs their ability to breathe and digest normally. This genetic disease is caused by a mutation of the CFTR gene (cystic fibrosis transmembrane conductance regulator). Everyone does have this gene, but only when it is mutated can it cause Cystic Fibrosis. Normally, the CFTR gene produces a protein whose job…

The Bodies exhibition showcases preserved human bodies dissected to display bodily system. The exhibit is set up so that one started at the skeletal system. The skeletal system showed the skeletal, the whole body bone include the ribs, large bone call femur and small bone call fibula, adult skull and infant skull. They also showed the prone bone that showed the bone disease as osteoarthritis and osteoporosis. Second system I learn is muscular system, the muscular system showed the muscular…
