Nerve impulses travel down the motor neuron and stimulate the appropriate leg muscle to contract. The response is a muscular jerk that happens quickly and does not involve your brain. Humans have lots of hardwired reflexes like this, but as tasks become more complex, the pathway circuitry gets...
Also, receptors carry the message of excess heat to your body's thermostat, the hypothalamus in the brain. Nerve impulses from the hypothalamus stimulate sweat glands in the skin to produce sweat. The fluid for the sweat also comes from the increased skin blood flow. The sweat evaporates from...
How does stimulus get to the hypothalamus and is the pathway considered somesthetic or autonomic? Is the response reflexive or intentional, cognitive or subconscious?The nervous systems and glands are related in that A) nerve cells can stimulate exocri...
The ability of GC and sex-hormones (estrogens, progesterone and testosterone) to modulate the immune system is well known. When the CNS detects systemic inflammation, the hypothalamus releases the corticotrophin releasing hormone (CRH) and arginine vasopressin (AVP), which stimulate the secretion of...
How does the hypothalamus control both the anterior and posterior pituitary functioning? The secretion of hormones by the anterior lobe of the pituitary gland is controlled by what? What is the normone produced by the hypothalamus that is secreted by the posterior pituitary to st...
How to Stimulate the Vagus Nerve Key Takeaways on Vagus Nerve Massage Benefits What is the Vagus Nerve? The vagus nerve, known as the “great wandering protector2,” is the longest cranial nerve in the body. It extends from the brainstem to organs such as the heart, lungs, digestive tract...
In particular, refined carbohydrates negatively impact metabolism and stimulate neural addiction mechanisms, which facilitate weight gain. As adipose tissue mass accumulates, satiation centers in the hypothalamus become resistant to insulin and leptin, which leads to increased caloric consumption. Several ...
What is the Third Eye? The pineal gland is a pea-sized gland shaped like a pine cone, located in the vertebrate brain near the hypothalamus and pituitary gland. Also known as the third eye, it is a revered tool of seers and mystics and considered to be the organ of supreme universal ...
Thehypothalamus, a small region in the middle of yourbrain, constantly processes information from your senses and transmits signals to the rest of your body through your autonomic nervous system. The signals can either relax (parasympathetic nervous system) or stimulate (sympathetic nervous system) ...
Oxytocin is a hormone normally created in an area of the brain called the hypothalamus. It also acts as a neurotransmitter, a chemical that brain cells use to communicate with each other. The wordoxytocinis derived from the Greek words “oxys” (quick) and “tokos” (birth), meaning “qu...
