What are the classification of tissues?

There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues).

How many classification of tissues are there?

Classifications of Tissues: The human body is composed of four basic types of tissues; epithelium, connective, muscular, and nervous tissues. These tissues vary in their composition and their function. A basic understanding of the role of each tissue makes understanding the specific functions easier.

What are the 4 types of tissue and their functions?

Epithelial tissues act as coverings controlling the movement of materials across the surface. Connective tissue integrates the various parts of the body and provides support and protection to organs. Muscle tissue allows the body to move. Nervous tissues propagate information.

What are 5 examples of tissues?

Tissues that work in unison to carry out a specific set of functions form an organ. Examples of plant tissues are meristematic tissues and vascular tissues. Examples of animal tissues are epithelial tissues, connective tissues, muscular tissues, and nervous tissues.

What is tissue with diagram?

Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial.

What are the main functions of tissues?

1 Functions of tissues
  • secretion.
  • movement.
  • strength.
  • excretion.
  • communication.

What type of tissue is bone?

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.

Who discovered tissue?

Xavier Bichat
Xavier Bichat introduced word tissue into the study of anatomy by 1801. He was “the first to propose that tissue is a central element in human anatomy, and he considered organs as collections of often disparate tissues, rather than as entities in themselves”.

Which organ has all 4 tissue types?

The four types of tissues are exemplified in nervous tissue, stratified squamous epithelial tissue, cardiac muscle tissue, and connective tissue in small intestine.

How many types of tissues are there class 9?

There are three types of permanent tissues: Simple Permanent Tissues. Complex Permanent Tissues. Special or Secretory Tissues.

What are the 4 types of cells?

The Four Main Types of Cells
  • Epithelial Cells. These cells are tightly attached to one another. …
  • Nerve Cells. These cells are specialized for communication. …
  • Muscle Cells. These cells are specialized for contraction. …
  • Connective Tissue Cells.

What are the classification of epithelial tissue?

Based on the cell shape, epithelial tissue is classified into squamous, cuboidal or columnar. Depending on the number of layers, the tissue is divided into simple or stratified. Subclassifications include pseudostratified, ciliated or transitional.

How do you classify connective tissue?

Connective tissue can further be broken down into three categories: loose connective tissue, dense connective tissue, and specialized connective tissue. Loose connective tissue works to hold organs in place and is made up of extracellular matrix and collagenous, elastic and reticular fibers.

What are the 7 functions of a cell?

Six Main Cell Functions
  • Provide Structure and Support. Like a classroom is made of bricks, every organism is made of cells. …
  • Facilitate Growth Through Mitosis. …
  • Allow Passive and Active Transport. …
  • Produce Energy. …
  • Create Metabolic Reactions. …
  • Aids in Reproduction.

What are the 3 shapes of cells?

The three principal shapes associated with epithelial cells are—squamous, cuboidal and columnar.
