the Endocrine System (known as ductless too...). This is composed of a lot of things... They are:pituitary gland - below the brain (master gland)‚ pineal gland - brain (It`s called the "third eye" by some‚ because its sensitive to light cycles)‚ hypothalamus - also in the brain (it works with the pituitary)‚ the thyrodic - neck (controls the metabolism)‚ adrenal - kidneys (responsible for the adrenaline)‚ pancreas - near stomach (produces insulin)‚ ovaries - on females and testes - on males (it produces
Premium Endocrine system Nervous system Central nervous system
The nervous system comprises the central nervous system which is made up of the brain and spinal cord‚ with the main functions being processing information and determining responses and the peripheral nervous systems which is made up of all sensory‚ motor and inter neurons within the body and these are located on peripheral nerves. All of them work together to collect sensory data and also control the actions of the body. Sensory neurons collect sensory information and convey it to the brain‚ and

If you electrically stimulate a rat’s lateral hypothalamus it will overeat. Student Response Value True 100% Score: 2/2 3. Orexin is released from the adrenal gland and stimulates hunger.

circadian rhythms is called chronobiology. The "master clock" that controls circadian rhythms consists of a group of nerve cells in the brain called the suprachiasmatic nucleus‚ or SCN. The SCN contains about 20‚000 nerve cells and is located in the hypothalamus‚ an area of the brain just above where the optic nerves from the eyes cross (Circadian Rhythms). Some of the factors that can affect a biological rhythm include delaying bedtime to socialize or finish reading a book‚ academic activities‚ employment

regulate the level of calcium in human body through production of hormones. 4. The hypothalamus’ function is to link the nervous system to the endocrine system via pituitary gland. The hypopthalamus is responsible for certain metabolic processes‚ including synthesizing secreting certain neurohormones‚ which are called hypothalamic-releasing hormones‚ which stimulate or inhibit secretion of pituitary hormones. The hypothalamus controls body temperature‚ hunger‚ thirst‚ fatigue‚ sleep and

MULTIPLE PITUITARY HORMONE DEFICIENCY | | Genetic Forms of Multiple Pituitary Hormone Deficiency. | | Quite a few genes involved in embryonic development are candidates to explain multiple pituitary hormone deficiency (MPHD) (Chapter 550). There are several distinctive heritable forms of MPHD. Mutations of transcription factor genes that are only expressed in the anterior pituitary lead to simple phenotypes with varying combinations of anterior pituitary hormone deficiencies

nonspecific stimulus (a "stressor"). This is converted into nervous signals that may be carried by any of many different neural pathways in the brain‚ but eventually it acts upon certain neuroendocrine cells in the paraventricular nucleus of the hypothalamus. These cells transform the nervous signals into a humoral messenger‚ (corticotrophin releasing hormone‚ CRH)‚ which is secreted from nerve endings into portal blood vessels which carry it to the anterior pituitary gland. There‚ CRH stimulates the

Oxytocin Oxytocin is a peptide hormone. It is produced by secreted from the posterior pituitary and synthesized in neurones paraventricular and supraoptic nuclei of the hypothalamus. The functions are contraction of uterine smooth muscle during labor. Contraction of myoepithelial cells around breast ducts and alveoli to stimulate milk flow and it is queried as to whether oxytocin release actually causes the onset of labor. Oxytocin primarily affects uterine smooth muscle - increasing both the

Discuss the Male Reproductive System The reproductive system is questionably the body system that is the most important influence on life as we know it. It is the w ay in which we procreate and ensure our existence as a species. However‚ the penis is only one part of the male reproductive system‚ which constitutes of a series responsible for generating‚ storing‚ and transporting the genetic material contained in the sperm cells. The main organs include: testicles (or testes)‚ the epididymides
