Study Notes
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
