- Neurons, like other cells, have a cell membrane that regulates the movement of molecules in and out of the cell.
- Neurons contain various organelles, such as mitochondria and endoplasmic reticulum, to support cellular functions like energy production and protein synthesis.
- Neurons have a nucleus that contains genetic material (DNA) and controls cellular activities, similar to other cells.

How many synapses occur in this reflex arc?
In a simple reflex arc, there are typically three neurons and two synapses. The sensory neuron carries the signal from the receptor to the central nervous system, where it synapses with the interneuron. The interneuron then synapses with the motor neuron, which carries the signal to the effector organ to produce a response.
What are the three parts of the cells theory?
The cell theory states that... 1. All living things are composed of cells. 2. Cells are the basic units of structure and functions in living things. 3. All cells are produced from other cells.
Identify two of the three assumptions in the Cell Theory?
1. Cells are the basic unit of structure in all living things.2. Cells carry on all life processes.even though you only said two...3. Cells are produced by other living cells.
What are the three types of cells that do not undergo mitosis?
The three types of cells that do not undergo mitosis are nerve cells (neurons), muscle cells (myocytes), and red blood cells (erythrocytes).
Name 3 types of white blood cells?
There are several types of white blood cells (leukocytes.) The 3 main groups are granulocytes, monocytes, and lymphocytes. There are 3 types of granulocytes; neutrophils, eosinophils, and basophils. There are 2 main types of lymphocytes; B cells and T cells. There are 4 types of T cells; cytotoxic T cells, helper T cells, suppressor T cells, and natural killer cells.

What is the basic unit of structure and functon of the nervous system?
The nervous system is used to trasmit information around the body. It is made of two systems: the central nervous system (which consists of the spine and brain) and the peripheral nervous system (which consists of neurones and receptors). There are three types of neurones: sensory neurones, relay neurons, and motor neurones.
What atre the three parts of thecell theory?
There are three parts of the cell theory. These three things consist of the fact that cells are units of life, living things are made up of 1 or more cells, and all cells come from other living cells.
What is idea called that all cells come from other cells?
It is one of the three ideas that make up the cell theory.
What are the three main cells in the body?
one is nucles i don't the other two
What are the three laws of the cell theory?
The three laws of the cell theory is: 1) All living things are composed of cells 2)Cells are the basic unit of structure and function in living things 3)Cells are made from other existing cells
What are three assumptions of cell theory?
The three assumptions of cell theory are 1: All cells form from other cells 2: A cell is the basic unit of life 3: All organisms are mad up of cells

Which cell is not a eukaryotes Plant cell animal cell Bacteria cell or trees cell?
Tree cells and plant cells are similar, and animal cells differ from the other three (tree, plant, and bacteria). Bacteria are characterized by having round DNA instead of linear DNA. Round DNA is a characteristic of prokaryotic cells and not eukaryotic cells. Thus, bacteria is not a eukaryote. (Note: there are many more differences between eukaryotic cells and prokaryotic cells such as size, organelles....)
Which of these is the odd one Neutrophil Erythrocyte Lymphocyte Macrophage?
Erythrocytes as they are to do with red blood cells. The other three are to do with white blood cells
