The Active Denial System (ADS) is a non-lethal directed-energy weapon developed by the U.S. military, [2] designed for area denial, perimeter security and crowd control. [3] Informally, the weapon is also called the heat ray [ 4 ] since it works by heating the surface of targets, such as the skin of targeted human beings.
In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. [1]
Neural top–down control of physiology concerns the direct regulation by the brain of physiological functions (in addition to smooth muscle and glandular ones). Cellular functions include the immune system’s production of T-lymphocytes and antibodies, and nonimmune related homeostatic functions such as liver gluconeogenesis, sodium reabsorption, osmoregulation, and brown adipose tissue ...
Spinal Cord Sectional Anatomy. WDR neurons are found in the posterior grey column of the spinal cord. [3] This area of the spinal cord houses two different types of neurons involved in the process of pain: WDR neurons and nociceptive specific neurons (NS). [4] As the name implies, NS neurons give specific short range responses. [5]
The central nervous system works closely with the body's endocrine system to regulate these mechanisms. The sympathetic nervous system becomes primarily active during a stress response , regulating many of the body's physiological functions in ways that ought to make an organism more adaptive to its environment.
In 2013, Raytheon demonstrated a ground-based air defense high-powered microwave system derived from CHAMP technology, disabling electronics on small UAVs. The demonstrator resembles the active denial system non-lethal crowd control device, including its reflector and steering mirror. It is integrated with radar automated tracking.
Axon terminals are specialized to release neurotransmitters very rapidly by exocytosis. [1] Neurotransmitter molecules are packaged into synaptic vesicles that cluster beneath the axon terminal membrane on the presynaptic side (A) of a synapse.
Autonomic nervous system, showing splanchnic nerves in middle, and the vagus nerve as "X" in blue. The heart and organs below in list to right are regarded as viscera. The autonomic nervous system has been classically divided into the sympathetic nervous system and parasympathetic nervous system only (i.e., exclusively motor).
