Unit 1. Chapter 2 Vocab

Contract

• A nerve cell

• To become big, especially by extending

• To become smaller or shorter

• To lengthen especially by pulling apart

Muscle Cell

• To become smaller or shorter, especially by pulling together the parts of something.

• A group of muscle cells that are bundled together, forming a larger unit

• The state of being free from tension or stress, the process of becoming less tense

• The basic building block of muscles, responsible for contraction and movement

Myosin

• A protein found in muscle cells that helps muscles contract by pulling on other proteins called actin.

• The thin outer layer that surrounds a cell, controlling what enters and leaves the cell.

• Relating to movement or motion.

• To become smaller or shorter, especially by pulling together the parts of something.

Neuron

• A protein found in muscle cells that helps muscles contract by pulling on other proteins called actin.

• A protein that is a major component of muscle fibers and is involved in muscle contraction.

• The basic building block of muscles, responsible for contraction and movement.

• A nerve cell that transmits electrical signals throughout the body.

Cell Membrane

• The thin outer layer that surrounds a cell, controlling what enters and leaves the cell.

Motor

• A nerve cell that transmits electrical signals throughout the body. 

• Relating to movement or motion.

• A thin thread or fiber, especially one that is part of a larger structure. 

• The state of being free from tension or stress; the process of becoming less tense.
