What is the most proximal part of the upper limb?
The most proximal part of the upper limb is the shoulder, specifically the shoulder girdle, which connects the upper limb to the trunk. This includes structures such as the clavicle (collarbone) and scapula (shoulder blade). The shoulder joint itself, where the humerus meets the scapula, is also considered a proximal feature of the upper limb.
The clavicle belongs to?
The clavicle belongs to the skeletal system and is a long bone that acts as a strut to hold the shoulder and upper limb in place. It connects the scapula to the sternum and is also known as the collarbone.
What factors account for the flexibility and mobility of the upper limb?
The flexibility and mobility of the upper limb are primarily due to the complex structure of the shoulder joint, which is a ball-and-socket joint allowing a wide range of motion. Additionally, the presence of numerous muscles, tendons, and ligaments contributes to both stability and dynamic movement. The arrangement of bones, including the scapula, clavicle, and humerus, along with the articulating surfaces, also enhances the upper limb's versatility. Finally, the neural control from the brain and spinal cord allows for precise and coordinated movements.
What organ does clavicle protect?
The clavicle, or collarbone, primarily protects the underlying structures of the shoulder, including the brachial plexus nerves and major blood vessels like the subclavian artery and vein. Additionally, it plays a role in stabilizing the shoulder joint, which is crucial for upper limb movement and function. By providing a bony barrier, the clavicle helps shield these vital components from injury during physical activity or trauma.
Which pulse is not detected in an upper limb?
The dorsalis pedis pulse is not detected in the upper limb, as it is located in the foot. In the upper limb, pulses such as the radial and ulnar can be palpated. The dorsalis pedis pulse is specifically associated with the lower limb's vascular system.
What double-curved bone acts as a strut for the shoulder girdle?
The clavicle, also known as the collarbone, is the double-curved bone that acts as a strut for the shoulder girdle. It connects the upper limb to the axial skeleton and provides stability and support for arm movements.
What is the most proximal part of the upper limb?
The most proximal part of the upper limb is the shoulder, specifically the shoulder girdle, which connects the upper limb to the trunk. This includes structures such as the clavicle (collarbone) and scapula (shoulder blade). The shoulder joint itself, where the humerus meets the scapula, is also considered a proximal feature of the upper limb.
Which one of the most frequently broken bones in the body transmits mechanical force from the upper limb to the trunk?
The clavicle.
What does a clavicle help you do?
The clavicle, or collarbone, plays a crucial role in connecting the arm to the body, providing support and stability to the shoulder. It facilitates a wide range of arm movements by acting as a strut that keeps the shoulder blade in place. Additionally, the clavicle helps protect underlying structures, such as nerves and blood vessels, that run from the neck to the upper limb. Overall, it contributes to both mobility and structural integrity in the upper body.
Shoulder girdle bone that articulates with and transmits forces to the bony thorax?
The clavicle is the shoulder girdle bone that articulates with and transmits forces to the bony thorax. It acts as a strut connecting the scapula to the sternum, allowing for movement and stability of the shoulder joint, as well as helping to transfer forces from the upper limb to the axial skeleton.
Is the shoulder proximal to the clavicle?
Your scapulae are not proximal to the midline of the body. They are lateral to the midline which is marked by the spine. Proximal and distal are used to indicate the position along an arm or leg. If some thing is close to the attachment to the body, that is proximal.
The clavicle belongs to?
The clavicle belongs to the skeletal system and is a long bone that acts as a strut to hold the shoulder and upper limb in place. It connects the scapula to the sternum and is also known as the collarbone.

Finally, the neural control from the brain and spinal cord allows for precise and coordinated movements.
What is the total number of bones in the pectoral girdle and the upper limb of one side?
There are a total of 4 bones in the pectoral girdle (scapula and clavicle) and 30 bones in the upper limb (humerus, radius, ulna, carpals, metacarpals, and phalanges) on one side of the body.
Shoulder girdle bone that acts as a brace and articulates with the axial skeleton?
The bone of the shoulder girdle that acts as a brace and articulates with the axial skeleton is the clavicle, commonly known as the collarbone. It connects the sternum (breastbone) at the manubrium to the scapula (shoulder blade), providing support and stability to the shoulder. The clavicle helps to transmit forces from the upper limb to the axial skeleton, playing a crucial role in maintaining the position of the shoulder.
What is the function of the claviele?
The clavicle, or collarbone, serves several important functions in the human body. It acts as a strut that connects the arm to the body, providing stability and support to the shoulder joint. Additionally, it protects underlying structures such as nerves and blood vessels, and it serves as an attachment point for various muscles involved in shoulder and arm movement. Overall, the clavicle plays a crucial role in facilitating upper limb mobility and function.
What is the purpose of the clavicle in human anatomy?
The clavicle serves several functions:It serves as a rigid support from which the scapula and free limb (arm) are suspended; an arrangement that keeps the upper limb away from the thorax so that the arm has maximum range of movement. Acting as a flexible, crane-like strut, it allows the scapula to move freely on the thoracic wall.Covering the cervicoaxillary canal, it protects the neurovascular bundle that supplies the upper limb.Transmits physical impacts from the upper limb to the axial skeleton.
