The neuroendocrine reflex is initiated by stimulation of sensory neurons that cause a release of a neurohormone from the neurosecretory cells. It is the simple neural reflex that controls the neuroendocrine reflex. The natural progression of events in this system is sensory nerves respond to a stimulus, be it thermal, tactile, or visual. These sensory nerves then synapse with interneurons in the spinal cord. Where efferent neurons, or neurons conducting impulses outwards from the brain or spinal cord, travel to the hypothalamus where the hypothalamic neurons release neurohormones. These neurohormones then enter the blood and activate the target tissues, such as the anterior lobe of the pituitary, mammary glands, or the epididymis. Senger, P.L.

What else can I help you with?
Milk letdown is a neuroendocrine reflex arc that requires which hormone?
Oxytocin is the hormone required for milk letdown. It is released from the pituitary gland in response to suckling or breast stimulation.
What hormone causes dwarfism or gigantism in children when levels are improprerly regulated?
The growth hormone is responsible for causing dwarfism or gigantism in children when levels are improperly regulated. Inadequate levels of growth hormone can lead to dwarfism, while excessive levels can result in gigantism. This hormone plays a crucial role in regulating growth and development in children.
What is Adenohypophyseal function regulated by?
Adenohypophyseal function is primarily regulated by the hypothalamus through the release of hormones such as corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone (TRH), and gonadotropin-releasing hormone (GnRH). These hormones stimulate or inhibit the release of specific hormones from the adenohypophysis, which in turn regulate various endocrine functions in the body.
What is the production of hormones from the pituitary gland regulated by?
The production of hormones from the pituitary gland is regulated by the hypothalamus, which secretes releasing and inhibiting hormones that control the release of hormones from the pituitary gland. Feedback loops involving target organs also help regulate hormone production by providing information on hormone levels in the body.
What is the gland in the brain that is regulated by light?
The gland in the brain that is regulated by light is the pineal gland. It responds to changes in light exposure, particularly through the production of the hormone melatonin which is involved in regulating the sleep-wake cycle.
What hormones is regulated by a neuroendocrine reflex oxytocin cortisol antidiuretic hormone?
oxytocin
Which hormones is regulated by a neuroendocrine (letdown) reflex?
The neuroendocrine "letdown" reflex is regulated by oxytocin.
What hormones is regulated by a neuroendocrine reflex?
oxytocin
Milk letdown is a neuroendocrine reflex arc that requires which hormone?
Oxytocin is the hormone required for milk letdown. It is released from the pituitary gland in response to suckling or breast stimulation.
How is anti diuretic hormone secretion regulated?
Antidiuretic hormone (ADH) is regulated by the pituitary gland. The anitidiuretic hormone maintains blood pressure and controls incoming water through the kidneys
What type of reflex does the secretion of the hormone insulin in response to changes in blood glucose levels?
Endocrine reflex
What mineral is regulated by calcitonin and parathyroid hormone?
calcium
What is ovulation regulated by?
Estrogen is the hormone. It is secreted by ovaries
What hormone causes dwarfism or gigantism in children when levels are improprerly regulated?
The growth hormone is responsible for causing dwarfism or gigantism in children when levels are improperly regulated. Inadequate levels of growth hormone can lead to dwarfism, while excessive levels can result in gigantism. This hormone plays a crucial role in regulating growth and development in children.
Parathyroid hormone regulated?
It increases the calcium level.It decreses the phosphste level.
What regulates growth through secretion of growth hormone?
Secretion of growth hormone (GH) in the pituitary is regulated by the neurosecretory nuclei of the hypothalamus.
Hormone production is self regulated by which mechanism?
Hormone production is self-regulated through a negative feedback mechanism. This means that when hormone levels in the blood reach a certain threshold, the body signals the glands to stop producing that hormone until levels drop back down. This helps maintain a balance of hormones in the body.
