CNS stimulants (CNS stands for central nervous system) are medicines that stimulate the brain, speeding up both mental and physical processes. They increase energy, improve attention and alertness, and elevate blood pressure, heart rate and respiratory rate.

What are the six classification of drugs?

When considering only their chemical makeup, there are six main classifications of drugs: alcohol, opioids, benzodiazepines, cannabinoids, barbiturates, and hallucinogens. Out of all the thousands of drugs that are out there, both prescription and illegal, each one can be categorized under one of these six headings.

How many types of CNS are there?

Cells that make up the Nervous System The nervous system can be divided into two sections – the central nervous system (CNS) and the peripheral nervous system (PNS).

What are the differences between CNS and PNS?

Central nervous system (CNS) consists of brain and spinal cord of the body. Peripheral nervous system (PNS) consists of dorsal and ventral root nerve cell heads, spinal and cranial nerves. Central nervous system (CNS) Controls all the voluntary functions of the body.

What are the four types of Neuroglia found in the CNS How are they different?

The four types of neuroglia found in the central nervous system are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. The two types of neuroglia found in the peripheral nervous system are satellite cells and Schwann cells. Neurons are the other the other type of cell that comprise nervous tissue.

What are the three structures of the CNS?

Central Nervous System Structure. The CNS has three main components: the brain, the spinal cord, and the neurons (or nerve cells).

What are the 4 stages of drugs?

No matter how long your journey is, most rehabilitation counselors agree that there are four main stages of drug addiction: experimentation, regular use, risky use/abuse, and drug addiction and dependency.

What are the three main functions the CNS and PNS carry out?

The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.

How does myelination differ in the CNS and PNS?

Myelination provides the electrical insulation of neurons. In CNS (central nervous system) oligodendrocyte is responsible for myelination of neuronal axons. These cells have processes that wrap around the axons to form myelin sheath. … In PNS (peripheral nervous system) myelin sheath is formed by Schwann cell.

What are the 6 types of Neuroglia?

• Astrocyte.
• Oligodendrocyte.
• Microglia.
• Ependymal cell.
• Satellite cell.
• Schwann cell.

What are the four types of supporting cells in the CNS?

The four types of neuroglia found in the central nervous system are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. The two types of neuroglia found in the peripheral nervous system are satellite cells and Schwann cells. Neurons are the other the other type of cell that comprise nervous tissue.

What are the main Neuroglia of the CNS and PNS?

Neuroglia in the CNS include astrocytes, microglial cells, ependymal cells and oligodendrocytes. Neuroglia in the PNS include Schwann cells and satellite cells. Astrocytes support and brace the neurons and anchor them to their nutrient supply lines.
