Detailed study of Frog by using Computer models
Aim:
To perform a detailed study of frogs using computer models.
Theory:
Frogs are the most commonly dissected animals below the university level other species used include cats, mice, rats, worms, dogs, rabbits, fetal pigs and fish.
Various alternatives to animal dissection are being used to meet the students’ needs in the classroom. The modern teaching methods, including interactive computer simulations and clay models: save animals’ lives, cost less than animal dissection, are suitable for all students, and are more effective than animal dissection.
Some of the commonly used alternatives/ computer simulations which can be used to perform a detailed study on frogs include digital frog 2.5.

DIGITAL FROG 2.5
It is a fully interactive CD-ROM that allows students to explore the frog through three seamlessly linked modules dissection, anatomy, and ecology.
V- Frog
It is the first virtual reality-based frog dissection software designed for biology education. Using a simple mouse and basic personal computer, a student can pick up a scalpel, cut and open the skin of the frog, and explore anatomy, physiology, and evolution, just like he or she would with a physical frog.
These programs can be used to study the systems of the body:
1. integumentary system deals with the study of skin and associated structures.
2. Muscular system deals with the study of skeletal muscle tissue and its attachment to bones.
3. Skeletal system deals with the study of bones and joints.
4. Nervous system deals with the study of the brain, nerves and special senses.
5. Cardiovascular system deals with the study of blood, heart and blood vessels.
6. Respiratory system deals with the study of organs of respiration and other air passages.
7. Digestive system deals with the study of organs of G.I.T. i.e. oesophagus, stomach,
small and large intestine.
8. Reproductive system deals with the study of male and female reproductive organs.
9. Excretory system deals with the study of organs for the excretion of waste products. Other systems are the lymphatic system and endocrine system.
In all, there are 11 systems in the body.
