Animal tissues can be classified into four main categories: muscular tissue, nervous tissue, connective tissue, and epithelial tissue. Muscular Tissue Muscular tissue is responsible for movement in the body and is found throughout various parts, including arms, legs, and chest. *Types of Muscular Tissue*: 1. *Skeletal Muscle*: Voluntary muscles that can be controlled consciously. Striated appearance due to the arrangement of fibers. Responsible for movements of limbs and body parts. 2. *Smooth Muscle*: Involuntary muscles that cannot be consciously controlled. Found in internal organs such as the stomach and bladder. Responsible for automatic movements like digestion and blood flow. 3. *Cardiac Muscle*: Involuntary muscle found only in the heart. Responsible for pumping blood throughout the body. Works continuously and rhythmically without conscious control. Functions of Muscular Tissue Allows movement in the body through contraction and relaxation. Contains specialized contractile proteins that enable muscle fibers to change shape, facilitating movement. Nervous Tissue Nervous tissue is essential for transmitting signals throughout the body. *Structure*: Composed of neurons (nerve cells) and glial cells (supporting cells). *Neurons*: Specialized cells that transmit information via electrical impulses. Consist of dendrites (short extensions) that receive signals and an axon (long extension) that transmits signals. *Glial Cells*: Support and protect neurons, ensuring their proper functioning. Functions of Nervous Tissue Transmits messages from sensory organs to the brain and from the brain to muscles. Coordinates responses to stimuli, allowing for reflex actions and voluntary movements. Key Differences Between Muscular and Nervous Tissue *Control*: Skeletal muscles are voluntary; smooth and cardiac muscles are involuntary. Nervous tissue controls and coordinates body functions through signal transmission. *Structure*: Muscular tissue consists of elongated cells (muscle fibers) that can contract. Nervous tissue consists of neurons and glial cells, with specialized structures for signal transmission. 🔔 SUBSCRIBE and GET it FREE:    / @free-educations
