Is a bone a tissue?

Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.

Do tissues form organs?

Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.

What are tissue made up of?

A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

Are all tissues composed of cells?

Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of body parts.

What are examples of tissues?

Animal Tissues

  • Epithelial Tissue. Cells of epithelial tissue form sheets that cover the body and organ surfaces.
  • Connective Tissue. Connective tissue consists of cells and non-living material, called the extracellular matrix.
  • Muscle Tissue.
  • Nervous Tissue.
  • Epidermis.
  • Vascular Tissue.
  • Ground Tissue.

What is the main characteristic of nervous tissue?

Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Two main classes of cells make up nervous tissue: the neuron and neuroglia (Figure 4.5. 1 The Neuron).

What are the two unique characteristics of nervous tissue?

Integration and communication are the two major functions of nervous tissue. Nervous tissue contains two categories of cells — neurons and neuroglia.

What is the function of nervous tissue in the skin?

The sensory nerves in the epidermis serve to sense and transmit heat, pain, and other noxious sensations. When these nerves are not functioning properly they can produce sensations such as numbness, pins-and-needles, pain, tingling, or burning.

What are the functions of muscular and nervous tissue?

The function of muscle tissue (smooth, skeletal, and cardiac) is to contract, while nervous tissue is responsible for communication.

What is the main difference between nerve tissue and muscles?

Complete answer:

PointsNervous tissueNervous system
FunctionThey transmit nerve impulsesIn the somatic system, nerves conduct impulses from sensory receptors located in the skin and internal organs to the CNS; nerves also conduct motor impulses from the CNS to the skeletal muscles.
