Hypothalamus

The Hypothalamus is a part of the Limbic system that directs a multitude of important functions in the body. It is roughly a size of a pearl, located just behind and between the eyes, below the thalamus and just above the brainstem. All vertebrates’ brain contains a hypothalamus, and it is highly interconnected with other parts of central nervous system. It links the nervous system to the endocrine system through the pituitary gland. This area of the brain is small, but involved in many necessary...

Hypothalamus

Regulation of distal organs such as the adrenal cortex. Anatomy Circle of Willis, above it is the hypothalamus; pituitary and pituitary stalk on either side of the 3rd ventricle. Pituitary is within the bony socket, at the base of the stalk. Salatarcica with the pituitary stalk passing down Cingulate gyrus and sulcus Fornix which comes out of the hippocampus Intraventricular foramen – in front of the thalamus and behind the fornix, through which CSF can pass through the ventricles. Aqueduct...

Essay On Hypothalamus

vertebrates, the hypothalamus, located at the base if the brain, plays a central role in integrating the endocrine and nervous systems. The hypothalamus receives information from nerves throughout the body and the brain. (Mousa and Mousa, 2003) In response, the hypothalamus initiates endocrine signalling appropriate to environmental conditions. In many vertebrates’ nerve signals from the brain pass information to the hypothalamus about seasonal changes, therefore the hypothalamus regulates the release...

Hypothalamus Gains Admittance

The hypothalamus is a small, vital section of the brain located just below the thalamus; it is in charge of numerous important bodily functions. The hypothalamus is shaped like a cone and ends in the pituitary stalk, a part of the pituitary gland. It forms the major portion of the ventral region of diencephalons, and oversees autonomic and metabolic processes. The hypothalamus is the connection between the nervous system and the endocrine system, creating this link by producing and secreting neurohormones...

Hypothalamus

Hypothalamus The hypothalamus may be very small, but it plays a very important role. The hypothalamus is about the size of a pearl, and it weighs about four grams in a brain that weighs on average about 1,400 grams. It directs so many important functions for the body some examples of what it controls are Autonomic function control , endocrine function control, Homeostasis, motor function control, food and water intake, body temperature, and the release of 8 major hormones. The hypothalamus...

The Hypothalamus

The Hypothalamus The hypothalamus is a small, but extremely important part of the brain. It is also known as the brain’s brain. It controls many different aspects of the body, and it is no larger than the size of a golf ball. This remarkable piece of the brain does so many different things for the body, so let’s study it. The Hypothalamus controls aspects of the endocrine, autonomic, and behavioral functions. (1) The hypothalamus controls the release of 8 major hormones, temperature regulation...

Powerpoint Intro To Endocrine System

longer durations • The hypothalamus regulates the pituitary gland through nerve stimulation • However, endocrine glands – which are stimulated by the pituitary gland – secrete chemicals that affect nerve activity of the hypothalamus Pituitary Gland (The Master Gland) • “master gland” because it controls the other endocrine glands • Located at the base of the brain; connected to the hypothalamus by a stalk • The pituitary produces and stores hormones • The hypothalamus stimulates release when...

Osmoregulation

potential of blood increases (e.g. large intake of water) -> An increase in osmotic pressure or decrease in water concentration in plasma Receptor: Hypothalamus stimulated -> Osmoreceptors in hypothalamus Modulator: Hypothalamus -> Sends message for release of ADH from posterior lobe of pituitary -> Nerve impulses from drinking centre of hypothalamus Corrective mechanism/effector: Less ADH released by pituitary gland into the bloodstream Less ADH transported to the kidneys Cells in the walls...

homeostasis function of the kidney

from cell in the body, the water potential of the blood is regulated to suit the individual; this is controlled by the hypothalamus. The hypothalamus is able to notice changes in the water potential off the blood that passes through the brain. This is process is carried out by the osmoreceptors cells in the hypothalamus. As a response to the change in water potential the hypothalamus controls the urge for thirds and further secrets a hormone called the antidiuretic hormone. The antidiuretic hormone...
