Furthermore, the innervation and blood supply of each muscle are meticulously detailed, ensuring a comprehensive understanding of neuromuscular control and vascularization.
Muscle Groups
The skeletal muscle system consists of various muscle groups that perform specific functions and movements. Each muscle group is composed of individual muscles that are located in different regions of the body.
| Muscle Group | Muscles | Location | Function | Innervation |
|---|---|---|---|---|
| Shoulder | Deltoid Supraspinatus Infraspinatus Teres minor Subscapularis | Shoulder | Abduction, flexion, extension, and rotation of the arm | Axillary nerve Suprascapular nerve Infrascapular nerve |
| Arm | Biceps brachii Triceps brachii Brachialis Coracobrachialis | Upper arm | Flexion and extension of the elbow joint | Musculocutaneous nerve Radial nerve Median nerve |
| Forearm | Flexor carpi radialis Flexor carpi ulnaris Extensor carpi radialis Extensor carpi ulnaris Pronator teres Supinator | Forearm | Flexion, extension, pronation, and supination of the wrist and fingers | Median nerve Ulnar nerve Radial nerve |
| Hip | Gluteus maximus Gluteus medius Gluteus minimus Tensor fasciae latae Iliopsoas | Hip | Extension, abduction, and rotation of the thigh | Inferior gluteal nerve Superior gluteal nerve Femoral nerve |
| Thigh | Quadriceps femoris (vastus lateralis, vastus medialis, vastus intermedius, rectus femoris) Hamstrings (biceps femoris, semitendinosus, semimembranosus) Adductor magnus Gracilis | Thigh | Extension and flexion of the knee joint | Femoral nerve Sciatic nerve Obturator nerve |
| Leg | Gastrocnemius Soleus Tibialis anterior Peroneus longus Peroneus brevis | Leg | Plantar flexion and dorsiflexion of the foot | Tibial nerve Common peroneal nerve Superficial peroneal nerve |
Muscle Actions: Table 10.2 Model Inventory For Skeletal Muscles
Muscles exert specific actions on joints, resulting in various movements. These actions are categorized and summarized in the following table:
| Muscle Name | Action | Joint Involved |
|---|---|---|
| Biceps brachii | Flexion | Elbow |
| Triceps brachii | Extension | Elbow |
| Gluteus maximus | Extension | Hip |
| Hamstrings | Flexion | Knee |
| Gastrocnemius | Plantar flexion | Ankle |
| Tibialis anterior | Dorsiflexion | Ankle |
Muscle Innervation
Muscles receive nerve impulses from the central nervous system through specific nerves. This innervation is crucial for muscle function and coordination.
| Muscle Name | Nerve | Type of Innervation |
|---|---|---|
| Deltoid | Axillary nerve | Motor |
| Biceps brachii | Musculocutaneous nerve | Motor |
| Gluteus maximus | Inferior gluteal nerve | Motor |
| Gastrocnemius | Tibial nerve | Motor |
| Tibialis anterior | Deep peroneal nerve | Motor |
Muscle Blood Supply
Muscles require a constant supply of oxygen and nutrients to function optimally. This supply is provided by arteries, while deoxygenated blood is drained through veins.
| Muscle Name | Artery | Vein |
|---|---|---|
| Deltoid | Axillary artery | Axillary vein |
| Biceps brachii | Brachial artery | Brachial vein |
| Gluteus maximus | Superior gluteal artery | Superior gluteal vein |
| Gastrocnemius | Popliteal artery | Popliteal vein |
| Tibialis anterior | Anterior tibial artery | Anterior tibial vein |
Clinical Relevance
Understanding the skeletal muscle system is crucial in various clinical settings. Muscle disorders can significantly impact movement and overall health.
- Muscle atrophy:Wasting or loss of muscle mass can occur due to inactivity, aging, or certain diseases.
- Muscle weakness:Inability to generate sufficient force, which can result from nerve damage, muscle disease, or electrolyte imbalances.
- Muscle cramps:Involuntary and painful muscle contractions that can be caused by dehydration, electrolyte imbalances, or nerve compression.
Exercise and Muscle Function
Exercise plays a vital role in maintaining and improving muscle function. Different types of exercise have specific effects on muscle mass and strength.
Resistance Training
Exercises involving resistance, such as weightlifting or resistance band exercises, stimulate muscle growth and increase strength. They work by causing micro-tears in muscle fibers, which repair and rebuild stronger.
Endurance Training, Table 10.2 model inventory for skeletal muscles
Activities like running, cycling, or swimming enhance cardiovascular fitness and increase muscle endurance. They improve the body’s ability to use oxygen efficiently and delay muscle fatigue.
Flexibility Training
Exercises that focus on stretching and flexibility, such as yoga or Pilates, improve muscle elasticity and range of motion. They help prevent muscle stiffness and injuries.
