What else can I help you with?
What cells of all animals are organized into structural and functional units called tissues EXCEPT for the?
Unicellular organisms. Tissues are formed by specialized groups of cells in multicellular organisms to perform specific functions, but unicellular organisms are not composed of different types of cells that can organize into tissues.
Tissues are organized into functional units called?
Tissues are organized into organs. Cells organized into tissues Tissues organized into organs Organs organized into organ system
Nervous tissue is made up of specialized units called?
Nervous tissue is made up of specialized units called nerve cells, or neurons. They detect different types of stimuli in the body.
Which tissues are made up of cells?
All tissues in the body are made up of cells. Cells are the basic structural and functional units of living organisms and are organized into specialized groupings to form tissues with specific functions.
Repeating units of actin and myosin filaments are called?
Repeating units of actin and myosin filaments are called sarcomeres. These are designed to control the contraction of muscles in the human body.
What is the structure of striated muscle cells?
Striated muscle cells, also known as skeletal muscle cells, are long cylindrical cells with multiple nuclei located at the periphery. They contain specialized structures called myofibrils, which consist of repeating units called sarcomeres. Sarcomeres are the functional units responsible for muscle contraction and are composed of thick and thin filaments made of proteins such as actin and myosin.
What is an increase in the number of active motor units in a muscle called?
recruitment
Increasing the number of active motor units is called?
Muscle recruitment
Does muscle tissue contain contractile units made of collagen?
No, muscle tissue contains contractile units made of actin and myosin proteins, which are responsible for muscle contraction. Collagen is a structural protein found in connective tissues like tendons and ligaments, but it is not directly involved in muscle contraction.
Which is true concering muscles tissue?
Skeletal muscle are muscles that are attached the bones. These muscles are designed to stretch and help the body to move.
What are muscle fibers that contains many bundles of cylindrical structure called?
Muscle fibers that contain many bundles of cylindrical structures are called myofibrils. Myofibrils are the contractile units within muscle fibers that are composed of repeating units called sarcomeres. Sarcomeres are responsible for muscle contractions by sliding past each other during the contraction process.
The filaments are arranged along the muscle fiber in units called?
Actin filaments
