Difference between epithelial and connective tissue:
|
Epithelial tissue
|
Connective tissue
|
|
Throughout the animal body, epithelial tissue lines the cavity and surfaces of organs and blood vessels.
|
Connective tissue in the body connects and separates various types of tissues and organs.
|
|
Cells in epithelial tissue are tightly packed together.
|
In connective tissue, cells are scattered around in an extracellular matrix.
|
|
It is located above the basement membrane.
|
It is located below the basement membrane.
|
|
The tissue developed from the germ layers of ectoderm, endoderm and mesoderm.
|
The tissue developed from the germ layer of the mesoderm.
|
|
They perform various functions that include protection, secretion, absorption, respiration and excretion.
|
It is responsible for supporting and connecting organs and tissues.
|
|
Blood capillaries do not exist in epithelial tissue.
|
Connective tissue encompassed blood capillaries that absorb nutrients.
|
|
It is located in the skin, glands, organs, mucous membranes, and organs like the kidney, intestine and lungs.
|
It is located in adipose, bone, tendons, ligament, nerves, cartilage and muscles.
|
Difference between muscular and nervous tissue:
|
Muscular tissue
|
Nervous tissue
|
|
Muscle cells are specialised cells found in muscles that can shorten their length using a set of motor proteins found inside the cell.
|
Nerve cells are granular cells that serve as the nervous system's functional unit, transmitting nerve impulses across the body.
|
|
It is also known as myocytes.
|
It is also known as neurons.
|
|
The cells are multinucleated, striated, long and cylindrical.
|
It is made up of cyton, axons, and dendrites.
|
|
The muscular system is composed of muscle cells.
|
The nervous system is made up of nerve cells.
|
|
Sarcolemma refers to the plasma membrane found in muscular tissue.
|
Neurolemma refers to the plasma membrane found in nervous tissue.
|
|
Sarcoplasm refers to the cytoplasm of muscular tissue.
|
Neuroplasm refers to the cytoplasm of nervous tissue.
|
|
Muscle contraction and relaxation are regulated by muscular tissue.
|
The nervous system is responsible for coordinating the body's functions.
|
|
Muscle tissue is divided into three types: Skeletal muscle, smooth muscle, and cardiac muscle.
|
Based on function, neurons are of three types: Sensory neurons, motor neurons and relay neurons.
|
Summary:
- Tissue is a set of cells that are structurally and functionally similar.
- Epithelial, connective, muscular, and nervous tissue are the types of animal tissues.
- Epithelial tissue is categorised as squamous, cuboidal, columnar, ciliated, and glandular based on its form and function.
- Areolar tissue, adipose tissue, bone, tendon, ligament, cartilage, lymph and blood are classified under connective tissues.
- Muscle tissues are classified as striated (skeletal), unstriated (smooth), and cardiac.
- Neurons that receive and execute impulses make up nervous tissue.
