Biology101: Nervous, Endocrine and Skeletal System udemy course

A Review Course for "O" level Biology Students

This introductory biology course explores how living organisms respond to their environment through the nervous, endocrine, and skeletal systems. Designed primarily for high school students—but open to anyone with an interest in the subject—it begins by examining how organisms detect and respond to changes in their surroundings. The course focuses first on the nervous system, particularly the structure and function of neurons and the human eye. Students will learn about common eye defects and how they can be corrected.

The course then shifts to the endocrine system, which works alongside the nervous system to help organisms adapt and survive. Learners will explore key differences between these two systems and understand their roles in maintaining internal balance and communication within the body.

In the final section, the course discusses the importance of movement in living organisms. Students will study the human skeletal and muscular systems and how they work together to produce motion.

Each section includes quizzes and sample questions with answers to support self-assessment and reinforce understanding. By the end of the course, students will have gained a solid foundation in how these essential body systems function and interact to support life.

This course is suitable for students preparing for examination and needs a quick revision of the topics .
