There are three types of filaments in the cytoplasm of most vertebrate cells: microfilaments, microtubules, and intermediate filaments. All of these filament systems share a critical feature: They are composed of proteins that have the unique property of being able to self-assemble into a filamentous network.
A biological unit of the body or of an organism. Examples of systems in human body: â¢ Circulatory system â¢ Digestive system â¢ Endocrine system â¢ Integumentary system â¢ Lymphatic system â¢ Muscular system â¢ Nervous system â¢ Reproductive system â¢ Respiratory system â¢ Skeletal system â¢ Urinary system.
The organ systems of the body include the musculoskeletal system, circulatory system, digestive system, endocrine system, integumentary system, urinary system, lymphatic system, immune system, respiratory system, nervous system and reproductive system. Organ Systems and Function, Location, Anatomy, Definition and Picture: 1  Skeletal System: The skeletal system is the system that supports us and gives us our shape.  Muscular System: The muscular system is the anatomical system of a species that allows it to move.
