Oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system are responsible for electrically insulating axons by forming myelin sheaths around them. This insulation increases the speed of conduction of nerve impulses along the axons.

What happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?
If additional dry cells are added in a circuit, the reading on both the ammeter and voltmeter will increase. This is because the added dry cells increase the voltage supplied to the circuit, causing an increase in current flow, which is reflected in the readings of the ammeter and voltmeter.
What happens to the current if the number of bulbs stays the same but you use more cells?
If you use more cells, the voltage across the bulbs will increase. This increased voltage will lead to an increase in the current flowing through the circuit, as current is directly proportional to voltage in Ohm's Law (I = V/R). So, the current through the bulbs will increase.
Do solar panels include convection conduction and radiation?
Solar panels primarily convert sunlight into electricity through photovoltaic cells. While conduction and radiation may play a small role in heat transfer within the panel, convection is typically not a significant factor due to the panel's design and low heat generation. The focus is on maximizing the efficiency of converting solar energy into usable electricity.
Why do you build solar cells in both parallel series and series configurations?
Solar cells in parallel series configuration are used to increase the current output, while solar cells in series configuration are used to increase the voltage output. By combining these configurations, you can optimize both current and voltage levels for a specific application, such as maximizing power output in a solar panel.
How does cartilage thickness increase?
Cartilage thickness can increase through a process called chondrogenesis, where chondrocytes (cartilage cells) produce more extracellular matrix components like collagen and proteoglycans. This leads to the growth and expansion of the cartilage tissue, resulting in an increase in thickness. Additionally, factors such as mechanical loading and appropriate nutrition can also support cartilage growth and increase its thickness.
What protects and insulates nerve fibers?
That is not the fatty 'material'. They are Glial cells derived from the mesoderm. The nerve cells are derived from ectoderm. The neural cells do not divide and so cancer do not arise from them. The malignancy in brain usually arise from these glial cells.
In a neuron the myelin sheath serves to insulate?
This insulation acts to increase the rate of transmission of signals. The Myelin Sheath of a neuron consists of fat-containing cells that insulate the axon from electrical activity.
What cell produces the myelin in peripheral nerves?
Schwann cells produce myelin in peripheral nerves. Schwann cells wrap around the axon of a neuron to form the myelin sheath, which helps to insulate and speed up the conduction of nerve impulses.
What cells insulate?
adipose maybe
Does The presence of endomysium results in skeletal muscle cells being electrically insulated from each other?
Yes, the endomysium is a connective tissue layer that surrounds individual muscle fibers. It helps insulate muscle fibers from each other electrically, allowing for more precise control over muscle contractions.
Supporting cells that insulate neurons and provide them with nutrients?
Glial cells
What is the specialized cells that myelinate the fibers of neurons found in the peripheral nervous system?
The specialized cells that myelinate the fibers of neurons in the peripheral nervous system are called Schwann cells. Schwann cells wrap around the axons of neurons to form the myelin sheath, which helps to insulate and protect the nerve fibers, allowing for faster and more efficient conduction of nerve impulses.
What is used to insulate the body and is found in cell membranes?
Lipids store energy, form the membranes around our cells, and insulate our body.
What does conduction cells mean?
It may mean cells that conduct impulses like nerve cells.
Is adipose tissue a dense connective tissue?
adipose are fat cells that insulate our body.
Are cardia muscle cells electrically connected by gap junctions and behave as a single unit?
Because cardiac muscle cells are electrically connected by gap junctions, the entire myocardium behaves like a single unit, a functional syncytium.
How does temperature on a physiological way effect nerve conduction?
Temperature can affect nerve conduction by altering the speed at which nerve impulses travel. Warmer temperatures typically increase the speed of nerve conduction, while cooler temperatures can slow it down. Extreme temperatures can also disrupt the integrity of the nerve cell membrane, impacting nerve conduction.
