Final Answer:
Clinical manifestations of median nerve damage include weakness or paralysis in the thumb, index, and middle fingers, known as the "ape hand" deformity. Additionally, individuals may experience sensory changes, such as numbness or tingling in the thumb, index, and middle fingers. These symptoms often arise due to conditions like carpal tunnel syndrome or injuries affecting the median nerve.
Step-by-step explanation:
Weakness or Paralysis (Ape Hand Deformity): Damage to the median nerve can result in weakness or paralysis in the muscles that control thumb movement, leading to a characteristic deformity known as the "ape hand."
Sensory Changes: The median nerve provides sensory innervation to the thumb, index, and middle fingers. Damage can cause sensations like numbness or tingling in these areas, affecting the ability to feel and manipulate objects.
Conditions Associated: Carpal tunnel syndrome is a common cause of median nerve damage, characterized by compression of the nerve in the wrist. Injuries or trauma to the forearm or hand can also lead to median nerve impairment.
