What is the term used to describe the complexity in organ and organ systems that displays a discernible trend?

What is the primary focus of the study of morphology?

What is the term used to describe the study of the internal structure of organs in animals?

Who is credited with coining the term 'animal tissue'?

What is the term used to describe the detailed study of tissues?

What is the function of muscular tissue?

What is the primary function of epithelial tissue?

Who is considered the father of histology?

Tissue Organisation

In multicellular organisms, basic tissues organise to form organs, which associate to form organ systems, enabling more efficient and coordinated activities of millions of cells.
Each organ in the human body is made up of one or more types of tissues.

Composition of Organs

The heart, for example, consists of all four types of tissues: epithelial, connective, muscular, and neural.

Evolutionary Trend

The complexity in organ and organ systems displays a discernible trend, known as the evolutionary trend.

Study of Organisms

The morphology and anatomy of three organisms at different evolutionary levels will be studied to demonstrate their organisation and functioning.
Morphology refers to the study of form or externally visible features.
In plants and microbes, morphology only refers to external features.
In animals, morphology refers to the external appearance of organs or body parts.
Anatomy is the study of the morphology of internal organs in animals.

Case Studies

The morphology and anatomy of earthworm, cockroach, and frog will be studied, representing invertebrates and vertebrates.

Tissue Basics

Cells in a tissue can differ in structure and function, but share a common origin.
The term "animal tissue" was coined by Bichat, while "plant tissue" was coined by Grew.
The study of tissues is called Histology, with Bichat as its father.

Types of Animal Tissues

Animal tissues are classified into four main types based on their structure and function:

Epithelial Tissue

Covers and protects the body
Functions as a barrier against external factors

Connective Tissue

Connects and supports structures in the body
Provides support and transports substances throughout the body

Muscular Tissue

Enables movement and locomotion through contraction and relaxation

Neural Tissue

No specific function mentioned in the text, but it is a distinct type of tissue in the body.

This quiz covers the organization of tissues to form organs and organ systems in multicellular organisms, highlighting their importance for efficient cellular activities. It also explores the composition of organs, such as the heart, which consists of various tissue types.
