Anterior pituitary

Study of the brain is significant in gaining insights on its structural and functional design and mechanisms which help explain the cause of various existing neurological and psychiatric diseases (Kotter, 2001). Consequently, the histological study of the nervous system and its components which underlies the understanding of the brain forms the basis and foundation of neuroscientific research (Annese, 2012). Important components of the nervous system include the spinal cord which consists of…

800 mL of net volume. The biological stress on astronauts and their bodies causes the increase of two hormones: ACTH (adrenocorticotropic hormone) and antidiuretic hormone. ACTH, as learned earlier in the semester, is a hormone secreted by the anterior pituitary gland and released in response to stress from the body. Recall that when our sympathetic nervous system is “turned on”, other activities in our body get put on the “back burner”, such as the body recognizing whether we are hungry or not,…

Brazilian Jiu-jitsu Brazilian Jiu-jitsu, or BJJ, is a style of martial arts, modified from the ancient Japanese art of Jiu-jitsu by the Gracie family and others, based on using an opponent’s momentum and leverage against them for defense. It involves take-downs and grappling, and has become a large sport that can be seen incorporated in the televised sport Mixed Martial Arts, or MMA. BJJ is a high intensity sport that involves endurance training as well as resistance training and explosive…

Researching the correlation amongst brain anatomy and physiology is a primary pursuit of neuroscience. Simplistic in its composition the brain is astoundingly the most complicated machine known to man. This mass of protein and fat in addition to being responsible for maintaining homeostasis also encompasses attributes that not only make us unique, creative, empathetic, moreover human. Overview of structure & function The brain of humans is primarily composed of two general classes of…

They are made within the nucleolus from 60% RNA and 40% protein, and consist of two subunits, one large and one small. When produced, the subunits stay separate to exit through the nuclear pores: it is only because of their miniscule size that they can fit through. Many ribosomes then bind themselves to the RER, although some stay free in the cytoplasm. Free and bound ribosomes both create polypeptide chains, which are used to make proteins. To create a polypeptide chain the large and small…

OESTRUS SYNCHRONISATION IN CATTLE SHELEMBE KHOLEKA INTRODUCTION Most beef and dairy farms in Africa use a pasture based breeding and calf rearing system which requires them to manage their herds such that calving and maximum milk production coincides with the period when the grass and pasture is good and nutritious which mainly occurs during spring and early summer (Xu et al., 1997; Lane et al., 2008). In order to maintain short breeding and calving seasons that would result in calving and peak…

Schizophrenia Assignment This essay will be focused on a mental illness known as Schizophrenia, which Jonathon is experiencing in the Case Study. It will outline its symptoms, the brain structures of Schizophrenic patients, how neurochemistry may be a possible causative factor in it and how medication can affect the brain structure and neurochemistry to manage symptoms in diagnoses of Schizophrenia. Schizophrenia is a serious chronic mental disorder which is described chiefly by defalcation in…

2014). These targets are receptor cells, which are either external and located on cell membranes or internal, within the cell (Herlihy, 2014). There are many glands throughout the body, with the main glands being the, hypothalamus, pineal gland, pituitary gland, thyroid gland, parathyroid gland, thymus gland, adrenal gland, pancreas and the gonads (Herlihy, 2014). The endocrine system is a vital system needed to function optimally to secrete hormones into the blood to be carried around the body…

The nervous system makes it possible for animals to know and react to the environment around them. A change or event that evokes a specific functional reaction in an organ or tissue is a stimulus. There can either be an internal or an external stimulus. Internal stimulus being something like hunger or pain, while external is more along the lines of a sound or an odor. The nervous system interprets stimuli and orders other organ systems to respond. The nervous system does so through using sensory…
