Are there any similarities between the upper and lower extremities?

Are there any similarities between the upper and lower extremities?

Both are long bones that end at the top with a ball and socket joint. This joint is used for mobility in both extremities. Even the pelvis and scapula are similar. Both are flat, weird shaped bones.

How are the upper and lower limbs different and how are they the same?

In the humans, the gross difference in the upper and lower limbs is that the flexor and extensor surfaces and their functional groups of muscles are in the opposite directions i.e. flexor surfaces or muscles in the upper limbs are placed anteriorly whilst in the lower limbs, it is the extensor surfaces or group of …

How are the forearm and the lower leg similar?

The forearm and the lower leg have two long bones each. In the forearm are the radius—on the thumb side of the forearm—and the ulna; in the lower leg are the tibia (the shinbone) and the fibula. The radius corresponds to the tibia and the ulna to the fibula.

What is upper limbs and lower limbs?

For anatomists, the upper limb consists of the arm (the upper arm), the forearm (the lower arm), and the hand. The arm consists of a single bone, the humerus. The forearm consists of two bones, the ulna and radius. And the hand consists of 27 bones, which are grouped into the phalanges, metacarpals, and carpals.

What are some signs of a serious extremity injury?

Symptoms of traumatic hand injuries and upper extremity injuries include:

  • Deformed or, in extreme cases, exposed bone.
  • Limited range of motion.
  • Numbness or tenderness.
  • Pain, swelling, or bruising.

What is the function of the upper limbs?

The primary purpose of the upper limb is to move the hand around the body during the activities of life. The shoulder girdle provides a wide range of motion—exceeding a hemisphere–so that the hand may reach in all directions.

Is blood pressure higher in the legs or arms?

Normally, the systolic blood pressure in the legs is usually 10% to 20% higher than the brachial artery pressure. Blood pressure readings that are lower in the legs as compared with the upper arms are considered abnormal and should prompt a work-up for peripheral vascular disease.

What are the bones between your legs called?

The leg has two bones: the tibia and the fibula.

What is considered upper limb?

The upper extremity or arm is a functional unit of the upper body. It consists of three sections, the upper arm, forearm, and hand. It extends from the shoulder joint to the fingers and contains 30 bones. It also consists of many nerves, blood vessels (arteries and veins), and muscles.

What are the two types of limbs?

In the human body, arms and legs are commonly called upper limbs and lower limbs, respectively. Arms are connected to the torso or trunk at the shoulder and legs are connected at the hip girdles.

What is a lower extremity injury?

The lower extremity is the anatomic area most commonly injured in sports. Injuries may occur from repetitive stresses associated with running and jumping or from acute traumatic events [1].

Can you have a broken leg and not know it?

Believe it or not, sometimes people can break bones and not realize it. Emergency room physician Dr. Troy Madsen says some bones are more prone to fractures. Swelling, trouble moving a joint, or lingering pain after a few days can all be indications of a bone fracture.

How are the biceps and hamstrings related to each other?

The biceps cross at the shoulder joint and assist in flexing. This mirrors the movement of the hamstrings in contraction. Even the gluteals of the hip joint mirror the deltoids of the shoulder joint. The front sections of both muscles pull their respective limbs forward and rotate internally.

What kind of muscles are on the upper arm?

On the upper arm, we have the triceps. they are called TRIceps because they are divided into three sections. Both share a common tendon that crosses the knee and elbow, respectively. Both muscles are also dedicated to extension. On the other side of the femur, or thigh, we have hamstrings which are a group of three muscles.

Are there any bones similar to the kneecap?

Even the pointy elbow works similarly to the kneecap. As we move up, we find the femur (leg) and the humerus (arm). Both are long bones that end at the top with a ball and socket joint. This joint is used for mobility in both extremities. Even the pelvis and scapula are similar. Both are flat, weird shaped bones.

Is the scapula similar to the pelvis?

Even the pelvis and scapula are similar. Both are flat, weird shaped bones. The clavicle and pubic bone also function quite similarly. The each connect the pelvis and shoulder girdle. In addition to structural similarities we will also find muscular similarities.
