The organized group of cells in a multicellular organism are referred to as tissues, these groups of cells that are similar functions together towards a specific task. When two or more tissues organize together to perform a particular function, these structures are referred to as organs, and groups of organs with specified functions from the organ systems. Animal tissue analysis is classified as histology, which includes the tissues’ microscopic structure and work. Animal tissues are broadly categorized into four types based on the structural and functional relationship which includes epithelial tissue, connective tissue, muscle tissue, and nervous tissue. These four types of tissues form the primary tissue types that work together for the organism’s health and function, a combination of two or more tissues forms the organ or organ system. The germ layers or the embryonic tissue layers formed during gastrulation are ectoderm, mesoderm, and endoderm. The epithelium of the animal cells is derived from the combination of these tissue layers.
The group of identical cells organized to execute a specific function is termed as tissues. The word tissue has been synthesized from ‘tissu’, a French word denoting ‘woven’ from the verb tisser something like ‘to weave’. Tissues are broadly categorized into four types based on structure-function analysis which includes epithelial, connective, muscle, and nervous. These tissues form as a primary type of tissue that together operates to promote the well-being and maintenance of the organisms. The disruption tissue may cause injury or disease. The tissues are composed of similar cells that are split from a common embryogenic origin. The successful fusion of the sperm with the egg results in a single large cell known as the zygote, the process of fusion of the cells is known as fertilization. During the development, the zygote divides into several cells resulting in the formation of an embryo. The ability of the embryonic cells produced that can differentiate into different body cells is known as omnipotent. Each embryonic cell can divide, differentiate, and develop into a new organism. In the course of development of the embryo as the proliferation progresses, three major cell lines are established in the embryo. The embryo gives rise to three germ layers that form the basics for the development of tissues or organs in the human body.
There are three major cell lines established in the embryonic cells as a result of the progression of the cell division. These cell lines give rise to the formation of germ layers. All cells and tissues of the animal cell are derived from these germ layers which include ectoderm, mesoderm, and endoderm. Animal tissues made up of these three layers are termed as triploblasts, there are animals with only two germ layers known as diploblasts. Animals such as jellyfish and comb jellies are examples of diploblast that lack mesodermal cells. The epithelial tissues originate from all three germ layers and different types of tissues are associated with these germ layers.
Ectoderm
The embryo is surrounded by a group of cells known as the ectoderm
Forms the precursor to mammary glands and nervous system
The ectoderm forms the outer linings of the body – epidermis, and hair.
Mesoderm
These are cells located in between the inner and outer layers of cells
It is responsible for evolutionary distinguishing of life forms with bilateral symmetry
It allows the formation of the internal body cavity in higher animals
The mesoderm gives rise to the dermis of the skin, the muscle system, the heart, the urogenital system, the bones, and the bone marrow.
Endoderm
These are formed by the inner layer of cells.
The endodermal cells pass through the embryo creating a continuous tract known as archenteron, which is also known as the embryonic gut.
The blastopore in protostomes is the embryo’s mouth while it forms the embryo’s anus in deuterostomes.
The endoderm develops into columnar cells present in the colon, the stomach, the intestines, the lungs, the liver, and the pancreas.
Types of tissues
The tissues are classified into four basic types which include connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
Epithelial tissue :
provides a covering through linings of the various passages inside the body
These are sheets of cell packed tightly that covers the body surfaces
The epithelial tissues consist of polarized cells.
The tip of the cell may be arranged either inside or outside the cavity, usually suspended in fluid or air.
The cells at the bottom are arranged towards the underlying cells.
Connective tissue :
These are cells suspended in an extracellular matrix.
The tissues are made up of protein fibers such as collagen and fibrin.
It supports and connects other tissues.
The common connective tissues are the loose connective tissue, that supports organs and blood vessels.
They comprise of dense or fibrous tissues that Dense, or fibrous, which attaches muscles to bones.
Connective tissues forms dedicated structures that include adipose tissue, bone, cartilage, and blood.
Muscle tissue :
It is essential for body structure and function.
The muscle fibers consist of proteins actin and myosin, which provide the ability for muscles to contract. Skeletal muscle, smooth muscle, and cardiac muscle are three types of muscle present in animals.
Skeletal muscle is made up of dense tissues attached to bones known as tendons, which control the movements consciously.
The heart walls are composed of cardiac muscle, and heart muscle function is unintentional.
Smooth muscles do not have conscious control and are involuntary.
The walls of the blood vessels, the digestive tract, the uterus, the urinary bladder, and numerous other structural components contain smooth muscle.
Nervous tissue:
It is implicated in sensing stimuli and processing or transmitting the information.
The nervous tissues consist of two major cell types known as neurons and glia.
The basic functional unit of the nervous system is the Neurons.
The primary function of glia is supporting neuronal function.
