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.
What two type of cell populations make up neural tissue?
Neurons and glial cells are the two main cell populations that make up neural tissue. Neurons are responsible for transmitting electrical impulses, while glial cells provide support and protection to neurons.
What kind of tissue is the iris made of?
loose aereolar connective tissue. this connective tissue is made up of 3 connective tissue fibres, collagen, elastic and reticular fibres. it contains fibroblast (most abundant cell type in connective tissue, which produces ground substance and fibres of connective tissue), macrophages, mast cells and plasma cells. its function is to hold and trap fluid, wrap and cushion organs and is important in inflammation.
How is a plant stem an example of an organ?
Because it has epithelial and connective tissue in it. Any organ has at least two of four types of tissues. Plant organs do not have muscle or nerve connective tissues. In human most of the organs have all four types of connective tissues.
What is composed of two or more tissues?
organ
An organ is a structure made up of two or more tissues working together to perform a specific function. Which of the following organs would contain the most nerve tissue according to its functional ro?
brain
Are muscles organs?
Yes. Muscles are made of a group of different tissues that support a common function. By that definition they are indeed organs. Most people think that only the internal organs are classified as organs, but organs are technically any body structure that is made of two or more tissues. Your muscles are made of muscle tissue and connective tissue called fascia.
Which two types of tissue present in skin?
Nerve tissue and Epithelial tissue would be my guess. But I am no expert, just a homeschooling mom.
Is lungs made of spongy tissue?
Yes, the lungs are made up of two spongy sac -like organs located in the upper chest that help in oxygenating the bloodstream.
Two or more different tissue combine to form?
Organs.

What type of tissue is located in the subcutaneous layer?
The subcutaneous tissue is the loose, connective tissue directly beneath the dermis. It is composed of adipose tissue or fat that is made up of lipocytes. These cells contain stored fat as an energy reserve. It also provides a layer of insulation to conserve internal body heat as well as a cushion to protect the bones and internal organs.
Organs are composed of two or more tissues?
The definition of an organ is that it is made up of quite similar types of tissue, all working together to serve a specific function. For example the tissue of parts of your brain are more similar to each other than they are to the tissue of any other organ. Likewise for kidney tissue, or the tissue of a blood vessel. This follows from the definition and naming of 'organ' - it has a purpose, even if not sentient in itself. But it does receive instructions and give off signals. Consider the word 'organize'.
How are cells tissue organ and organ system related?
Cells are the smallest unit of life. Large groups of cells with the same purpose are called tissue, groups of tissue with the same purpose form organs, organs with similar purposes form systems and systems form organisms.
What do you call two or more tissues together form?
Two or more tissues together form an organ. Organs are structures that perform specific functions within an organism and are composed of various types of tissues working collaboratively. For example, the heart is an organ made up of muscle tissue, connective tissue, and nervous tissue.
Which tissues work together to form muscles?
Two or more tissues working together is an organ.
What is the relationships between cell tissue organs and systems in the body?
Cells of similar type come together to form tissues. Two or more types of tissue come together to form organs. Organs that work together perform a common function are known as organ systems.
