Muscle and Nervous Tissue Overview

Skeletal Muscle Tissue

• Striated and voluntary muscle
• Attached to bones enabling movement
• Responsible for locomotion and body posture
• Contains multiple nuclei per cell

Cardiac Muscle Tissue

• Striated and involuntary muscle
• Found exclusively in the heart
• Cells connected by intercalated discs, facilitating synchronized contractions
• Single nucleus per cell, with branching fibers

Smooth Muscle Tissue

• Non-striated and involuntary muscle
• Located in walls of hollow organs (e.g., intestines, blood vessels)
• Responsible for involuntary movements like digestion and blood flow
• Spindle-shaped cells with a single nucleus

Neuron

• Fundamental unit of the nervous system
• Specialized for signal transmission
• Composed of cell body, axon, and dendrites

Nucleus

• Control center of the neuron
• Contains genetic material (DNA)
• Essential for cell function and maintenance

Cell Body

• Also known as the soma
• Houses the nucleus and organelles
• Integrates incoming signals from dendrites

Axon

• Long, slender projection of a neuron
• Transmits electrical impulses away from the cell body
• Can be myelinated for faster signal conduction

Dendrites

• Branch-like extensions from the cell body
• Receive signals from other neurons and synapses
• Increase surface area for information reception
