The topic covers the detailed anatomy of the upper limb muscles, focusing on their roles in movement and stability. The upper limb muscles are divided into different groups based on their location and function:

### 1. **Shoulder Muscles (Musculi Humeri)**

The shoulder muscles surround the shoulder joint, with the **rotator cuff** being crucial for movement and stability. Key muscles include:

- **Supraspinatus**: Abducts the arm at the shoulder, innervated by the suprascapular nerve.

- **Infraspinatus** and **Teres Minor**: Both muscles externally rotate the arm, innervated by the suprascapular and axillary nerves.

- **Subscapularis**: Internally rotates the arm, innervated by the subscapular nerves.

### 2. **Arm Muscles (Musculi Brachii)**

The arm muscles are split into anterior and posterior groups.

#### Anterior Group:

- **Biceps Brachii**: Flexes the elbow and supinates the forearm, innervated by the musculocutaneous nerve.

- **Brachialis**: Primary elbow flexor, innervated by the musculocutaneous and radial nerves.

- **Coracobrachialis**: Flexes and adducts the arm, innervated by the musculocutaneous nerve.

#### Posterior Group:

- **Triceps Brachii**: Extends the elbow, innervated by the radial nerve.

### 3. **Forearm Muscles (Musculi Antebrachii)**

The forearm muscles control wrist and finger movements and are divided into anterior, lateral, and posterior groups.

#### Anterior Group:

- **Superficial Layer**: Includes **Flexor Carpi Radialis**, **Palmaris Longus**, and **Pronator Teres** that control wrist flexion and forearm pronation.

- **Deep Layer**: Flexes fingers and thumb, including **Flexor Digitorum Superficialis** and **Flexor Pollicis Longus**.

#### Lateral Group:

- **Brachioradialis**: Flexes the elbow, innervated by the radial nerve.

- **Extensor Carpi Radialis Longus and Brevis**: Extend and abduct the wrist.

#### Posterior Group:

- **Extensor Digitorum**: Extends the fingers.

- **Supinator**: Supinates the forearm.

### 4. **Hand Muscles (Musculi Manus)**

The hand muscles are responsible for fine motor control and are divided into three groups:

#### Thenar Muscles (Thumb Movement):

- **Abductor Pollicis Brevis**, **Flexor Pollicis Brevis**, **Opponens Pollicis**, and **Adductor Pollicis** control thumb movements, innervated by the median and ulnar nerves.

#### Hypothenar Muscles (Little Finger Movement):

- **Abductor Digiti Minimi**, **Flexor Digiti Minimi**, and **Opponens Digiti Minimi** control little finger movements, innervated by the ulnar nerve.

#### Intermediate Muscles:

- **Lumbricals**: Flex the metacarpophalangeal joints and extend interphalangeal joints.

- **Interossei**: Control finger abduction (dorsal) and adduction (palmar), innervated by the ulnar nerve.

### 5. **Axillary Region (Armpit)**

The axillary region is a pyramidal space between the upper arm and chest, housing critical structures like the **axillary artery**, **brachial plexus**, and **axillary lymph nodes**. It is bounded by:

- **Anterior Wall**: Pectoralis major muscle.

- **Posterior Wall**: Latissimus dorsi, teres major, and subscapularis muscles.

- **Medial Wall**: Serratus anterior muscle.

- **Lateral Wall**: Humerus.

The axillary space allows the passage of vital nerves and blood vessels to the upper limb, making it an essential structure for upper limb function.

In summary, the upper limb's anatomy consists of several muscle groups that work together to enable a wide range of movements, from gross motor functions like shoulder abduction and elbow extension to fine motor skills in the hand. The axillary region serves as a passageway for critical structures that support these functions.

General Structure of the Vertebra

Each vertebra has the following parts:

1. **Corpus vertebrae**: The main body, filled with spongy bone and red marrow, supporting weight.

2. **Arcus vertebrae**: The vertebral arch, attached to the body, protecting the spinal cord.

3. **Processus spinosus**: The spinous process, a bony projection from the arch, providing muscle attachment.

4. **Processus transversi**: Lateral projections for muscle attachment.

5. **Foramen vertebrae**: The vertebral foramen, a hole housing the spinal cord.

### Divisions of the Spine:

1. **Cervical Vertebrae (C1-C7)**: Neck vertebrae allowing significant movement. The **Atlas (C1)** supports the skull, and the **Axis (C2)** enables head rotation.

2. **Thoracic Vertebrae (T1-T12)**: Chest vertebrae, supporting the ribs.

3. **Lumbar Vertebrae (L1-L5)**: Lower back vertebrae, larger and designed for weight-bearing.

4. **Sacrum**: A triangular bone formed by the fusion of five sacral vertebrae, connecting the spine to the pelvis.

5. **Coccyx**: The tailbone, formed by fused coccygeal vertebrae, has no arches but retains small projections.

The lower limb skeleton is a complex and vital part of the human body, responsible for supporting weight, providing mobility, and maintaining balance. It begins with the pelvis, which connects the spine to the lower limbs. The pelvis consists of three fused bones—the ilium, ischium, and pubis—that meet at the acetabulum, forming the hip socket. This socket connects with the head of the femur, creating the hip joint, which allows for a wide range of movements like flexion, extension, abduction, and rotation.

The femur, the longest and strongest bone in the body, plays a critical role in transmitting the body's weight from the pelvis to the lower leg. At its distal end, the femur articulates with the tibia and patella to form the knee joint. This joint is supported by crucial structures, including the menisci (shock-absorbing cartilage) and multiple ligaments like the cruciate and collateral ligaments, which provide stability during movement.

Below the knee, the tibia and fibula form the lower leg. The tibia is the main weight-bearing bone, while the fibula provides lateral stability and serves as an attachment site for muscles. Both bones are connected by the interosseous membrane, and at their distal ends, they form the ankle joint, which is supported by strong ligaments.

Moving down, the foot consists of three sections: the tarsal bones (including the heel bone or calcaneus and the talus), the metatarsal bones, and the phalanges (toe bones). The foot is uniquely structured to support the body's weight, facilitate walking, and maintain balance through its arches. Important ligaments, such as the plantar ligaments and ligamentum bifurcatum, stabilize the foot and ankle joints, ensuring that movements like inversion, eversion, and flexion are smooth and controlled.

Understanding the anatomy of the lower limb skeleton is essential for comprehending how the body supports itself, moves, and responds to various forces during everyday activities such as standing, walking, running, and jumping.
