Is nerve cells an organ?
No, nerve cells are not organs. Nerve cells, also known as neurons, are the basic building blocks of the nervous system and are responsible for transmitting information throughout the body. The nervous system, which includes the brain, spinal cord, and nerves, is the organ system in which nerve cells are found.
What is composed of 1 or more cells?
An organ is composed of one or more cells.
What compose an organism?
The organism is composed of the organ system and the organ system is composed of organs that work together and the organs are composed of tissues and the tissues are composed of cells and the cells are composed of molecules
Is the brain a multicellular organism?
No, the brain is not a multicellular organism. It is an organ within a multicellular organism, such as a human or animal, composed of billions of individual cells called neurons that work together to control various functions within the body.
What organ composed mainly from epithelial and nervous tissues converts vibrations that are sent to the brain?
The ear is the organ composed mainly of epithelial and nervous tissues that convert vibrations into electrical signals that are then sent to the brain for processing and interpretation. The inner ear contains hair cells that help to detect sound waves and convert them into nerve impulses that travel to the brain via the auditory nerve.
Is a typical organ made up of different kinds of cells and tissue?
Yes. Organs are composed of tissues, and tissues are composed of cells.
Organ systems can be composed of cells or tissues but not both?
This statement is incorrect. Organ systems are composed of organs, which are made up of tissues that are in turn composed of cells. Cells work together to form tissues, tissues form organs, and organs work together in organ systems to carry out specific physiological functions in the body.
Is a nerve a organ?
A nerve cell is a cell all by itself. There are two kinds of nerve cells, neurons and neuroglia. A single nerve cell can be part of a group of similar nerve cells and be considered a tissue; as in a nerve, which is composed of many nerve cells. But, if there is more than one kind of tissue that contributes to a common function, then we call that an organ. The the heart is an organ because it has several kinds of tissues that all work together. Nerves contain a network of nerve cells that carry signals and impulses to the spinal cord and the brain. These are called afferent neurons. They also carry signals away from the central nervous system (CNS), these are called efferent neurons.
Which organ's job has mostly to do with sending and receiving messages using nerve cells?
brain
In what organ would you find the most nerve tissue?
Skin is the largest organ of the body and also has the most nerve endings.
