What else can I help you with?
Is neurons capable of anaerobic metabolism?
Yes, neurons have the ability to perform anaerobic metabolism, particularly during periods of high energy demand or when oxygen supply is limited. However, neurons primarily rely on aerobic metabolism for their energy needs due to their high metabolic activity and constant energy requirements.
Most neurons lack centrioles This observation explains?
the inability of most neurons to undergo cell division. Centrioles are required for the organization of the mitotic spindle during cell division. Since neurons lack centrioles, they are unable to divide and are primarily post-mitotic cells.
How are neurons similar to other cells?
Neurons, like other cells, have a cell membrane that regulates what goes in and out of the cell. They also contain organelles such as the nucleus, mitochondria, and endoplasmic reticulum to perform various cellular functions. Additionally, neurons reproduce through cell division like other cells in the body.
Do neurons require oxygen to function properly?
Yes, neurons require oxygen to function properly. Oxygen is essential for the production of energy in neurons through a process called cellular respiration. Without enough oxygen, neurons can become damaged and may not be able to communicate effectively with other cells in the brain.
Are neurons are able to divide?
No, you're thinking of Neuroglia

What type of neurons form the afferent division of the PNS?
Sensory neurons form the afferent division of the peripheral nervous system. These neurons carry sensory information from the body to the central nervous system.
What neurons form the afferent division of the PNS?
For CH 12 of A&P the correct answer is: Sensory Neurons.
The nervous system cells or neurons do not contain centrioles These neurons most likely could not what?
Neurons lacking centrioles are unlikely to be able to undergo cell division. Centrioles are important for organizing the cell's cytoskeleton during mitosis, and their absence could hinder cell division in neurons.

Which division of the nervous system has short preganglionic neurons?
sympathetic
What happens to the neurons when there is a lack of oxygen?
When there is a lack of oxygen, neurons are unable to produce energy through aerobic metabolism. As a result, they switch to anaerobic metabolism, leading to the build-up of lactic acid and a decrease in ATP production. Prolonged oxygen deprivation can ultimately lead to cell death and irreversible damage to the neurons.

What types if cells are invovled in mitochordria?
Mitochondria are found in almost all eukaryotic cells, including animal, plant, and fungal cells. They are particularly abundant in cells with high energy demands, such as muscle cells and neurons. Mitochondria contain their own DNA and are involved in energy production through ATP synthesis, making them crucial for cellular metabolism. Additionally, they play roles in apoptosis and calcium signaling within various cell types.
What is the key supply source of energy for neurons?
Glucose is the key supply source of energy for neurons. Neurons rely heavily on glucose to generate the adenosine triphosphate (ATP) needed for their cellular functions, including transmitting signals throughout the nervous system.
What are the chemical levels of organization of neurons?
Neurons are organized at the molecular level with structures like receptors and ion channels, which facilitate their communication. At the cellular level, neurons interact through neurotransmitters and signaling pathways. At the network level, neurons form circuits and synapses that allow for complex information processing and transmission.
Do neurons require oxygen to function properly?
Yes, neurons require oxygen to function properly. Oxygen is essential for the production of energy in neurons through a process called cellular respiration. Without enough oxygen, neurons can become damaged and may not be able to communicate effectively with other cells in the brain.
