Living with Damage to the Hypothalamus Essay

The thyroid is a part of the endocrine system. The thyroid produces two hormones that affect metabolism, heart function and brain development. The hormones also helps regulate body temperature, weight and skin dryness. The two hormones that the thyroid secrets is triiodothyronine (T3) and thyroxine (T4). Thyroid-Stimulation hormone (TSH) is secreated by the pituitary gland, also part of the endocrine system, regulates the production on thyroid hormoes. If thyroid hormones are low the pituitart gland releases more TSH and if the thyroid hormones are hign less TSH is released. If someone is has Hashimoto’s disease the function of the thyroid and pituitary gland is affected and starts to decrease the thyroid hormones in the body and causes the pituitary gland to release more TSH into the

The hypothalamus is the part of the brain that regulates body temperature, emotions, hunger, thirst, sleeping and waking. This part of the brain also controls the pituitary gland and regulates hormones. Damage or loss to the hypothalamus will most likely result in unusual happenings with your hormones.

The pituitary gland is apart the endocrine system. The pituitary is also a master gland in the brain. The endocrine system sends hormones throughout the body in the blood stream. The hormones in our body play an important role. They influences our interests in many things, such as the food that we like to eat. They also affect many other tissues in the

Pituitary gland - lies in a small pocket of bone at the skull base called the sella turcica. The pituitary gland is connected to the hypothalamus of the brain by the pituitary stalk. Known as the “master gland,” it controls other endocrine glands in the body. It secretes hormones that control sexual development, promote bone and muscle growth, respond to stress, and fight disease.

Hypothalamo-Pituitary Gonadal Axis (HPG) is the path where the gonads communicate with the hypothalamus and pituitary glands to stimulate development.The hypothalamus functions through the gonadotropin-releasing hormone (GnRH) which stimulates the pituitary glands for different actions. During stress, glucocorticoids are released as a hormonal response. They suppress production of GnRH in a path where the hippocampus inhibits the functioning of the hypothalamus. This downregulates the HPG axis reducing sexual excitement and repressing the working

Homeostasis is continually being disrupted due to the external environment, whether it be the weather causing the body to overheat/sweat or a blood glucose level dropping due to missing a meal. Luckily, there are body systems that work together to bring the internal environment back to the right balance. The nervous system and the endocrine system are linked with the hypothalamus, which is situated in the centre of the brain it provides the needed corrective measures to ensure the body is back to the right balance. When homeostasis is maintained, we know that the body is healthy.

It secretes hormones that regulate bodily function; it also produces oxytocin and antidiuretic hormone (ADH). The pituitary gland is located below the hypothalamus and works in conjunction with it. The pituitary gland releases hormones that regulate the endocrine system. The endocrine system regulates body processes by releasing chemical messages called hormones, therefore is responsible for hormone regulation. The adrenal glands are located above the kidneys and are apart one of the endocrine glands. When the body receives a message form the hypothalamus or pituitary gland (stimulation) the hormones are secreted as the response. These messages are transmitted through a synapse. A synapse is the space between the end of an axon (carries impulses away from the cell) and the cell body that receives the neuron (receives and transmits electrochemical pulses). The nerve impulse is sent from the hypothalamus and sent to the presynaptic axon and then the neurotransmitter diffuses across the synaptic cleft to the receptors on the postsynaptic membrane. Neurotransmitters are chemicals that permit the transmission of messages between

The hypothalamo-pituitary-adrenocortical (HPA) axis is a critical adaptive system that maximizes survival potential in the face of physical or psychological challenge. The principal end-products of the HPA axis, glucocorticoid hormones, act on multiple organ systems, including the brain, to maintain homeostatic balance. Ryan Jankord and James P. Herman LIMBIC REGULATION OF HYPOTHALAMO-PITUITARY-ADRENOCORTICAL FUNCTION DURING ACUTE AND CHRONIC STRESS

The nervous system and the endocrine system connect- the endocrine system hormones provide feedback to the brain to affect neural processing enabling the nervous system to work. The endocrine system also enables the hypothalamus which is a portion of the brain that contains a number of small nuclei with a variety of functions to control the pituitary gland and other endocrine glands in order to interact with the nervous system; therefore it is vital the interrelationship between the nervous and endocrine systems in order for the nervous system to carry messages to and from the brain and spinal cord to various parts of the body and for the endocrine system to function well by the made up of glands to produce and secrete hormones, chemical

The endocrine is highly reacting to the stress. It is body sources in response to the threat after taking signals from the brain, the hypothalamus sends the order to the pituitary gland, and the pituitary gland releases stress hormones into the blood stream to reach their targets within minutes or even hours, and exert prolonged effects. Those stress hormones transportation through the bloodstream and by the stress hormones will activate other stress hormones (Stressdirections, 2016).

Pituitary control thyroid hormone level, thyroid hormone is a pea-sized gland in the brain. Pituitary and hypothalamus communicate to maintain T3 and T4 balance. Pituitary makes thyroid stimulating hormone (TSH), releasing more TSH when T3 and T4 levels are low by contrast pituitary release less if T3 and T4 levels are high.

During states of stress, the endocrine responses in two parallel paths. One path, termed the adrenocortical response, is controlled by the sympathetic nervous system; and the other is the adrenomedullary response which is controlled by the hypothalamus - the part of the brain that triggers the release of different stress hormones - and pituitary gland (Lovallo, 2015; Sarafino & Smith, 2011). In the adrenocortical response, the hypothalamus sends a message to the sympathetic nerves that is mediated by the brain stem, this in turn activates the adrenal medulla which secretes epinephrine (adrenaline) that prepares the body for a fight or flight response (Lovallo, 2015).

The lobe that connects the hypothalamus to the anterior pituitary is called the hypophyseal portal

The hypothalamus is located just below the thalamus and is in control of regulating homeostasis within the body. It monitors states of rest, temperature, hunger, thirst, through the controlled release of hormones it maintains an internal balance; any shift out of balance results in diminished cognitive processes (Sousa, 2011). A child with autism for example, who is averse to sudden changes in environment, would likely respond erratically to a fire drill. This sudden change and over stimulus could result in an adrenaline response and sudden change in

The hypothalamus transmits nerve impulses that go through brain stem, spinal cord, and preganglionic sympathetic nerve fibers to adrenal medulla, then will
