20
Q

What is the 1 nerve involved in the Carpal Tunnel?

A

The median nerve.

It is one nerve that is part of the Brachial Plexus group. It travels down the medial arm. Runs anterior to the medial epicondyle of the Humerus. It runs down the anterior forearm and through the carpal tunnel. It serves digits 1, 2, 3 and part of 4.

21
Q

What is the Brachial Plexus?

A

Consists of spinal nerves C5 through T1.

22
Q

What is Carpal Tunnel Syndrome (CTS?)

A

Through repetitive use of the flexors, inflammation develops within the carpal tunnel. This impinges the medial nerve which results in tingling, numbness, pain and eventual loss of use of the lateral hand (digits 1, 2, 3 and part of 4).

36
Q

What is the sciatic nerve made up of?

A

Spinal nerves L4 through S3.

Largest nerve in the body. Serves flutes, posterior thigh and entire leg. It branches just above the popliteal region into the tibial and common fibular nerves.

37
Q

What is sciatica?

A

Impingement of the sciatic nerve by soft tissue or bone. Occurs in the lower lumbar/upper sacral regions. Causes tingling, numbness, pain and eventual loss of use of the lower extremity.

38
Q

What is piriformis syndrome?

A

Impingement of the sciatic nerve through the greater sciatic notch by the piriformis muscle. Causes symptoms similar to sciatica.

A

1 muscle + IT band

45
Q

What are the 2 Anterior/Lateral Thigh muscles?

A
  1. Iliotibial Band; and 2. Tensor Fascia Latae
