Study Notes
Muscular Tissue
- Muscle cells are termed muscle fibers.
- Muscle bundles form the structural unit.
- The cell membrane is called the sarcolemma.
- Sarcoplasm contains abundant cytoplasm.
- Skeletal muscle fibers are found in the tongue, diaphragm, and the walls of blood vessels and respiratory tract.
- Skeletal muscle connective tissue is differentiated into epimysium (muscle bundles), perimysium (covers each muscle bundle), and endomysium (covers individual muscle fibers).
- Skeletal muscle fibers have a cylindrical, striated shape.
- Skeletal muscle fiber nuclei are multiple, oval, and located peripherally.
- Sarcoplasm is rich in rough endoplasmic reticulum, contains transverse striations.
- Key features of skeletal muscle fibers under a microscope include multiple oval central nuclei, and transverse striations which are due to longitudinal mitochondria.
- Sarcoplasmic reticulum forms a network around the mitochondria.
- Sarcoplasmic reticulum participates in forming the triad tubular system.
Myofibrils
- Myofibrils contain organelles like mitochondria and rough endoplasmic reticulum.
- Myofibrils show alternating dark and light bands.
- The dark band is called the A band, and the light band is called the I band.
- The A band is bisected by the H zone.
- The I band is bisected by the Z line.
- The H zone, present within the A band, is bisected by the M line.
- The sarcomere is the segment from one Z line to the next.
Types of Muscle Tissue
- Smooth muscle fibers are characterized as non-striated, involuntary.
- Skeletal muscle is characterized by striations and voluntary control.
- Cardiac muscle has intercalated discs, branching fibers, and is involuntary.
- Smooth muscle is found in the respiratory, digestive, and urinary systems.
- Cardiac muscle is located in the heart.
- Skeletal muscle has spindle-shaped cells.
- Red muscle fibers are resistant to fatigue and rich in myoglobin; they primarily use aerobic respiration.
- White muscle fibers are fast-twitch and get their energy primarily from glycogen; they primarily use anaerobic respiration.
Additional Information
- Sarcolemma is the plasma membrane.
- Endomysium covers each muscle fiber.
- Myosin is a myofilament.
- The outer connective tissue covering of a muscle is the epimysium.
- Muscle fibers contain actin and myosin.
- Skeletal muscle has a lot of mitochondria.
- Cardiac muscle has branching cells.
- Perimysium covers muscle bundles.
