Mascular System & Tissues

The Muscular System

T: Muscular System
- D: Responsible for movement and posture; works with the skeletal system.
T: Skeletal Muscle
- D: Voluntary muscle; attached to bones; controls body movement.
T: Smooth Muscle
- D: Involuntary muscle; found in organs and blood vessels; controls digestion and circulation.
T: Cardiac Muscle
- D: Involuntary muscle; found in the heart; pumps blood.
T: Muscle Contraction
- D: Muscles work by contracting and relaxing to create movement.

Tissue Types and Their Functions

T: Epithelial Tissue
- D: Covers body surfaces, lines cavities, acts as a barrier, and controls material exchange.
T: Examples of Epithelial Tissue
- D: Skin epithelium (protection), digestive tract lining (absorption), sweat glands (secretion).

T: Connective Tissue
- D: Supports, binds, and protects tissues and organs.
T: Loose Connective Tissue
- D: Provides cushioning and connects skin to underlying tissues (e.g., Areolar tissue).
T: Dense Connective Tissue
- D: Provides strong support (e.g., Tendons connect muscle to bone; Ligaments connect bone to bone).
T: Cartilage
- D: Provides flexibility and support (e.g., Hyaline cartilage in joints).
T: Bone (Osseous Tissue)
- D: Provides structure, stores minerals, protects organs.
T: Blood
- D: Transports oxygen, nutrients, waste; part of immune response.
T: Adipose Tissue (Fat)
- D: Stores energy, insulates, and cushions organs.

T: Muscle Tissue
- D: Responsible for movement and force generation.
T: Skeletal Muscle
- D: Voluntary movement; attached to bones.
T: Smooth Muscle
- D: Involuntary movement; found in organs and blood vessels.
T: Cardiac Muscle
- D: Involuntary movement; found in the heart.

T: Nervous Tissue
- D: Transmits electrical signals and controls body functions.
T: Neurons
- D: Nerve cells that send electrical signals.
T: Glial Cells
- D: Support and protect neurons.
T: Examples of Nervous Tissue
- D: Brain, spinal cord, peripheral nerves.
