Takeaways

• 😀 The skeletal muscle system is composed of around 640 muscles that are crucial for various bodily functions like movement and reaction.
• 😀 The trapezius muscle has three portions: superior, middle, and inferior, and it spans from the neck down the back.
• 😀 The deltoid muscle is divided into three parts: anterior, lateral, and posterior, helping in lifting the arms.
• 😀 The biceps is a flexor muscle made up of two parts: the short and long heads.
• 😀 The triceps, an extensor muscle, consists of three parts: lateral, long, and medial heads.
• 😀 The pectoralis major muscle moves the humerus, while the pectoralis minor helps lift the ribs.
• 😀 The rhomboid muscles on the upper back allow for shoulder movements and are made up of minor and major parts.
• 😀 The latissimus dorsi muscles are the widest in the back and contribute to various back movements.
• 😀 The obliques help in torso rotation, with the external obliques being visible and the internal obliques lying beneath them.
• 😀 The rectus abdominis, often referred to as abs, helps in flexing the spine and contributes to core stability.
• 😀 The gluteal muscles (maximus, medius, and minimus) are the largest muscles in the rear, assisting in movements like climbing stairs.
• 😀 The quadriceps, consisting of four muscles (vastus lateralis, intermedius, medialis, and rectus femoris), help extend the knee.
• 😀 The hamstrings, made up of three muscles (biceps femoris, semitendinosus, and semimembranosus), help in leg flexion.
• 😀 The calf muscles, including the soleus and gastrocnemius, with their lateral and medial heads, are important for activities like cycling.

Q & A

What is the role of the skeletal muscle system?

The skeletal muscle system is responsible for contraction, enabling you to fight, react, and perform various movements. It is composed of around 640 muscles that work together to support different actions.

What are the three portions of the trapezius muscle?

The trapezius muscle has three portions: superior, middle, and inferior. These portions are located in the neck and upper back area.

How are the deltoid muscles divided?

The deltoid muscles are divided into three parts: anterior (front), lateral (middle), and posterior (rear). They are responsible for lifting the arms.

What is the function of the biceps and how is it structured?

The biceps function as a flexor muscle, composed of two sections: the short head and the long head. These muscles are responsible for bending the arm at the elbow.

What are the three parts of the triceps muscle?

The triceps muscle is an extensor with three parts: lateral, long, and medial heads. It helps extend the arm at the elbow.

What is the difference between the pectoralis major and minor muscles?

The pectoralis major helps move the humerus, while the pectoralis minor lifts the ribs. Both muscles are located on the chest and work in coordination.

Where are the rhomboids located and what is their function?

The rhomboids are located on the upper back, between the shoulder blades. They help in scapular retraction, allowing for improved movement and posture.

What is the role of the latissimus dorsi muscles?

The latissimus dorsi muscles are the largest muscles in the back and are located on either side of the torso. They play a significant role in movements like shoulder extension and rotation.

What muscles are involved in abdominal rotation?

The obliques, which consist of the external and internal oblique muscles, are responsible for abdominal rotation. They help in twisting the torso.

What are the three muscles of the glutes, and what do they do?

The three gluteal muscles are the gluteus maximus, medius, and minimus. They play an important role in movement, especially in actions like climbing stairs, standing, and walking.
