1. A. Homeostasis is defined as a condition of equilibrium in the body internal environment. For example the internal organs‚ behaviors‚ body temperatures. In homeostasis it can be considered as dynamic as it is always changing. The liver‚ kidneys‚ autonomic nervous system and endocrine system‚ and hypothalamus help maintain homeostasis. For example‚ my brother has imbalance homeostasis due to having seizures. Because his brain is not functioning correctly‚ his homeostasis is not balance. B. Medial

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters.

skeletal muscles. Because these nerves permit conscious control of the skeletal muscles‚ it is sometimes called the voluntary nervous system. The autonomic nervous system supplies motor impulses to cardiac muscle‚ to smooth muscle‚ and to glandular epithelium. Because the autonomic nervous system regulates involuntary or automatic functions‚ it is called the involuntary nervous system. The brain is the source of all our behavior‚ thoughts‚ feelings‚ and experiences. In humans‚ the brain weighs about

Bronchodilators are important in the treatment of airways disorders such as chronic obstructive pulmonary disease (COPD) and asthma and critical in the management of the disorders symptoms. There are 3 major classes of bronchodilators currently in use‚ namely xanthines‚ β2- adrenoceptor agonists and muscarinic receptor antagonists (2). Examples of drugs which fall into these classes are discussed later. They can be taken on their own or in combination. The relaxation/contraction of smooth muscle

Acute Hydropes-Corneal edema resulting from tears Due to ruptures of the descemet`s membrane and acute seepage of the aqueous humor into the corneal stroma and epithelium. These breaks usually heal within 6-10 weeks and the edema gradually clears. 11. Variable corneal scarring‚ depending on severity of the disease.

Complications Following the creation of an oroantral communication‚ the communication diameter usually decreases over time but often the ‘tract’ from the antrum to the mouth fails to heal and becomes lined by epithelium. Once this occurs the communication is referred to as a fistula. This fistula acts as a pathway for infection and can result in the development of acute sinusitis which further prolong the healing
