This is because it secretes various hormones that control all the other glands in the body when stimulated by the hypothalamus. It also produces hormones that regulate the growth rate of children and awaken the sexual glands at puberty. The Pineal gland is located near to the center of the brain. It produces a hormone known as serotonin. Research has shown that serotonin to affect different parts of the body depending on how much of it is being secreted and possible combinations with enzymes and other hormones.
The Pituitary Gland The body contains a system for communicating, coordinating and controlling the bodies work. This is known as the endocrine system. The endocrine system works together with other systems and glands in the body to maintain and control body energy levels, reproductions, growth and development, homeostasis and responses to stress and injury. To maintain these functions, a network of glands and organs produce, store, and secrete certain hormones to complete different body functions. Hormones, which are chemical messengers, transfer information from one gland to another for important body functions.
The human body produces hormones which act as “chemical messengers” to try to regulate certain bodily functions like metabolism and growth. These hormones are produced in the endocrine system which includes the adrenal, pancreas, pineal, pituitary, and thyroid glands and manage things like puberty, growth, and physical changes. Hormones help the body maintain homeostasis or a state of balance within the body. When the body produces to much or to little of a hormone it can cause both physical and emotional problems. The growth rate of children is for the most part controlled by the hormones produced from the thyroid and pituitary glands.
This is important statement because it proves that gender identity and sexual orientation is not purely choice, but driven by biological forces. Because hormones play such a diverse role in bodily functions, I will break down hormones into categories to provide clarification. Hormones are chemicals that come from the endocrine gland and are released into the circulatory system (Pinel, 2009). Hormones affect other endocrine glands or various parts in the nervous system. There are three types of hormones: amino acids, peptides and proteins, and steroids (Pinel, 2009).
Tissue Types Within the Human Body Nervous Tissue The nervous tissue is found in the nervous system, and includes the brain, spinal cord and nerves through out the organism. The tissues main function is to carry messages throughout the body, gathering and feeding back information via electronic impulses along specialised cells called neurones. Like an information highway it synchronizes the working of the nervous system by sending messages, to ensure that the all the body's systems work together, maintaining the constant internal conditions needed and enabling the body to respond to external stimuli. The basic unit of structure of nervous tissue is the neuron, consisting of a nerve cell body and several processes: dendrites, which carry impulses toward the nerve cell body, and axons, which carry impulses away from the cell body. Neurons receive signals from either the external or internal environment, and transmit them in the form of electrical impulses to other neurons, muscles or glands.
Damage to these areas of the brain can change a person’s behaviour for example damage to the frontal lobe can affect personality. Another assumption of the biological approach is behaviour can be explained in terms of hormones. Hormones regulate different behaviours. Hormones are biochemical substances that are produced by endocrine glands such as pituitary glands and adrenal glands. Hormones are transported through the blood stream to various organs and tissues.
Noradrenergic neurons project bilaterally (send signals to both sides of the brain) from the locus ceruleus along distinct pathways to many locations, including the cerebral cortex, limbic system, and the spinal cord, forming a neurotransmitter system. Norepinephrine is also released from postganglionic neurons of the sympathetic nervous system, to transmit the fight-or-flight response in each tissue respectively. The adrenal medulla can also be counted to such postganglionic nerve cells, although they release norepinephrine into the blood. Norepinephrine system The noradrenergic neurons in the brain form a neurotransmitter system, that, when activated, exerts effects on large areas of the brain. The effects are alertness and arousal, and influences on the reward system.
The first stage of the stress response occurs when the hypothalamus in the brain detects stress and switches on the Sympathetic Nervous System (SNS) to induce a rush of adrenaline. The (SNS) activates body functions involved in the stress response by releasing Noradrenaline via the sympathetic nerves and Adrenaline and Noradrenaline via the Adrenal Medulla. These neurotransmitters work to increase heart rate, blood pressure, cellular metabolism and bronchial dilation with a view to ensuring that adequate oxygen, nutrients and energy supplies are delivered to essential organs in preparation for an emergency response. Moreover, these chemical messengers are also responsible for vasoconstriction of blood vessels which inhibit the functioning of the digestive system; this prevents blood from being diverted from essential
The brain is responsible for all control over the body, even the production of hormones. The pituitary gland plays a significant role by releasing two hormones that encourage growth. One of the hormones that the pituitary gland produces that is involved in the child’s growth is the thyroid-stimulating hormone (TSH). This hormone cues the thyroid gland to release thyroxine (which is necessary for brain development and for other hormones to have its full impact on the body). Infants born with a deficiency of thyroxine must receive it at once or they will be mentally retarded.
Therefore, we need to learn how to develop and take care of our emotional health, this involves emotional intelligence. One component of emotional intelligence is the ability; ability to monitor ones self. Which involves being in tune with what you are actually feeling, and being aware of the emotions you are experiencing. It means that you give attention to the information you gather as a result of be aware of your thoughts and feelings. You also need the ability able to access yourself.
