L3 | MUSCULAR SYSTEM
Cards (22)
- MUSCULAR SYSTEM
- Produces movement.
- The human body has more than 600 muscles.
- By alternating between contraction and relaxation, muscles cause bones and supported structures to move.
- TONING
- Increase the size of muscles
- Removal of fat cells on muscular cells
- PROTAGONIST MUSCLE
- Muscles that are relaxed
- ANTAGONIST MUSCLE
- Muscles that contracts
- FUNCTION
- MOVEMENT
- STABILITY
- CONTROL OF BODY OPENINGS AND PASSAGES
- HEAT PRODUCTION
- TYPES OF MUSCLE TISSUE
- SKELETAL MUSCLE
- SMOOTH MUSCLE
- CARDIAC MUSCLE
- SKELETAL MUSCLE
- Location: Attached to bones and skin of the face
- Function: Body movements and facial expressions
- Mode of control: Voluntary
- Features:
- Fibers: striated, tubular, and multi nucleated
- STRIATION
- Nerve endings
- SMOOTH MUSCLE
- Location: Walls of hollow organs, blood vessels, and iris
- Function: Moves contents through organs; vasoconstriction
- Mode of control: Involuntary
- Features:
- Fibers: non striated, spindle shaped, and uninucleated
- CARDIAC MUSCLE
- Location: Wall of the heart
- Function: Pumps blood through heart
- Mode of control: Involuntary
- Features:
- Fibers: striated, branched, and uninucleated
- MUSCLE GROWTH AND ADAPTATION
- HYPERTROPHY
- ATROPHY
- EXERCISE AND NUTRITION
- HYPERTROPHY
- Increase in muscle size
- ATROPHY
- Reduction in muscle mass
- EXERCISE AND NUTRITION
- Crucial for muscle growth
- MUSCLE DISORDERS
- MUSCLE STRAINS
- DYSTROPHIES
- MYOPATHIES
- MUSCLE STRAINS
- Result from overstretching or tearing muscle fibers
- DYSTROPHIES
- Genetic disorders characterized by progressive muscle weakness and degeneration
- MYOPATHIES
- Encompass various disease that affect muscle function
- PERISTALSIS
- Rhythmic contraction that pushes substances through tubes of the body.
- Muscle fibers in visceral smooth muscle respond to neurotransmitters but they also stimulate each other to contract.
- Muscle fibers tend to contract and relax together.
