A type of tissue that sends electrical signals through the body?
Nervous tissue is composed of neurons that use electrical signals to transfer impulses throughout the body.
When was the first cable tv invented?
Cable TV was invented as a response to poor over the air reception. In 1948, companies in Arkansas, Oregon, and Pennsylvania started sending TV signals down coaxial cables.
What are hybrid signals?
Hybrid signals are the combination of both analog and digital signals
Proteins each of which has a three dimensional shape complementary to that of a specific signal molecule?
You are likely referring to receptor proteins. Receptor proteins are used extensively in the endocrine, nervous and immune systems to carry out signal transduction and communication between cells. For example, an endocrine receptor may be the insulin receptor, which dimerizes upon signal molecule (insulin) binding and induces a series of changes in the cell leading to increased glucose uptake, increased glycolysis and decreased gluconeogenesis. A nervous system receptor may be a neurotransmitter receptor located at synapses that induces an action potential in the downstream neuron if it binds to a neurotransmitter released by the upstream neuron. The immune system makes extensive use of receptors and these receptors may be cell-surface bound or even soluble (e.g. antibodies). They are involved either in recognizing foreign molecules, transmission of activation signals for leukocytes, or administration of death (apoptosis) signals to other kinds of cells.
Describe the role of the myelin sheath?
Myelin sheath is the insulation of the CNS (central nervous system). Its helps electrical signals move along nerves. Basically, its synonymous with insulated wire. Again the insulation help the signal move in a smooth and controlled fashion through out the body.
Is the The peripheral nervous system responsible for both sending and receiving signals to and from the brain?
yes
Which body system is responsible for sending signals that the body should react to immediately?
nervous
What is integrative?
the nervous system responds by sending signals to muscles, causing them to contract, or to glands, causing them to produce secretions
What are evoked potential studies?
Evoked potential studies measure the electrical activity in the brain in response to specific stimuli, such as visual or auditory signals. They can provide valuable information about the function of the nervous system, including detecting abnormalities in sensory processing or tracking the progression of diseases like multiple sclerosis. These studies are non-invasive and can help diagnose conditions affecting the brain and nervous system.
What is integrative function?
the nervous system responds by sending signals to muscles, causing them to contract, or to glands, causing them to produce secretions
What system allows you to feel pain?
The human nervous system allows us to experience pain. When our body detects potential harm or injury, specialized nerve receptors called nociceptors send signals to the brain, which interprets these signals as pain.
What is the purpose of evoked potential studies?
Nerves convey information to the body by sending electrical signals down the length of the nerve. These signals can be recorded by wires placed over the nerves on the surface of the skin, in a procedure called an evoked potential (EP) study.
How the Endocrine system and the nervous system work together to maintain homeostasis?
The endocrine and nervous system work together to maintain homeostasis by sending each other signals and messages to know when the body needs something.
Shes confused and is sending mixed signals?
She is sending this mixed signals because she does not know yet if she is ready for a relationship with you. Maybe she is because you are the one sending mixed signals and she is because she does not know if you like her.
What tissue transmits electrical signals?
neurons
Is the spinal cord the brain of the brain?
Nope! The spinal cord connects the brain to the rest of the nervous system in the body, sending and receiving signals. It is a conduit, nothing more.
Briefly explain the function of the nervous system?
The nervous system's ultimate function is to interpret and respond to sensory signals from the environment.The nervous system consists of two main categories:1. Peripheral Nervous System (PNS): receives sensory stimuli, passes stimulus information to CNS in the form of an electrical action potential.2. Central Nervous System (CNS): consists of brain and spinal cord; interprets signals coming from sensory stimuli in the periphery and decides appropriate response to initiate- Afferent neurons transmit sensory signals from the PNS to the CNS- Efferent neurons transmit response signals to targets in the body to respond accordingly to initial sensory stimulus.
