The endocrine system consists of mainly the pituitary and pineal glands in the brain, the thyroid and parathyroid in the throat, the thymus gland which is located near the heart, the adrenal and sexual glands. The hypothalamus also plays an important role in stimulating certain hormones from the pituitary gland. On a lesser degree neurons also secrete hormones into the bloodstream. The pituitary gland lies close to the hypothalamus of the brain and is often referred to as the master gland. This is because it secretes various hormones that control all the other glands in the body when stimulated by the hypothalamus.
Hormones, which are chemical messengers, transfer information from one gland to another for important body functions. When the receptor is stimulated, the cell responds to the hormone in specific ways. Endocrine hormones are secreted into the bloodstream, while exocrine hormones are secreted into a duct and go through paracrine signaling. Hormones have many different effects on the body such as mood swings, metabolism regulation, control of the reproductive system, hunger cravings and many others. The glands which are involved in the endocrine system
While the SNS directs the movements of the skeletal muscles, the ANS regulates involuntary processes such as the heart beating, breathing, blood pressure, and blood sugar level. When compared to other animals’ brains, the human brain is a more complex central nervous system. The reason for this is due to the proficiency of the human brain to continuously develop both in the structure and function of numerous cells in it as a responsive mechanism towards new incoming information, experiences, and even shock, which is also known as brain plasticity.

Some common disorders affecting the central nervous system. These neurological disorders include multiple sclerosis, Alzheimer's disease, Parkinson's disease, epilepsy, and stroke, and can affect memory and ability to perform daily activities. The CNS is made up of the brain, brain stem, and spinal cord. The brain is the main data center of the body and consists of the cerebrum which regulates higher level functioning such as thought, and the cerebellum which maintains coordination. The central nervous system is protected in many ways.
Tumors on the Hypothalamus What is a Hypothalamus? : Hypothalamus is a small area near the base of the brain just ventral to the thalamus. It is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the nervous system to the endocrine system via the pituitary gland. It has widespread connections with the rest of the forebrain and the midbrain.
Through apolipoprotein C-II, the mature chylomicrons activate lipoprotein lipase (LPL). Lipoprotein lipase is an enzyme found on the endothelial cells that line the blood vessels, which catalyzes the hydrolysis of triacyglycerol (glycerol covalently bonded to three fatty acids). Triacyglycerol releases glycerol along with fatty acids found in the chylomicrons. Fatty acids and glycerol can be absorbed in muscle, peripheral tissues, and adipose, for energy as well as storage. The hydrolyzed chylomicrons become chylomicron remnants.
Brain Trauma The cerebellum plays an important role in motor output and sensory perception. It integrates pathways in the brain that send information to muscles and provides feedback of the position of the body in space. The cerebellum plays a role in muscle tension important for maintaining posture and fine finger movement such as typing. The cerebellum also plays a role in cognitive function including attention, processing of language and music and other temporal sensory stimuli. It also regulates fear and pleasure responses.
A conclusion will then be drawn based on the discussion. The brain is an essential organ of the body. It is the control center for all the body’s activities, such as walking, talking, swallowing, breathing taste, smell and heart beat. The brain also controls our thinking functions, our intellectual activities as well as our emotions. Hemispheric specialization refers to the dominance of one hemisphere of the brain in specific functions, such as language, emotions, motor control and so on ( Feldman, 2009).
Briauna pope The Extrapyramidal System The extrapyramidal system is a neural network apart of the motor system. It controls all involuntary movements, reflexes and coordination. This system lies in the reticular formation of the pons and medulla to target the nerves living in the spinal cord. The system works by modifying neural impulses that come from the cerebral cortex which are then sent to the systems nuclei; basal ganglia. To work, the extrapyramidal system centers on the modulation and regulation of anterior horn cells.
The Nervous System Neuroscience is critical in understanding addiction because it’s how our different body parts communicate. Psychoactive drugs affect the brain as a result of the processes of the nervous system as it receives senses, is able to transmit because it's interconnected, and initiates responses. The Central Nervous System is comprised of the Brain and the Spinal Cord. The nervous system is in essence a biological information highway, is the controller of all the biological functions and movement in the body, and can also receive information and interpret it. This is done through electrical signals which are used in the nervous system.
