Research:
The carpal region is inside of the appendicular region which is connected to the upper and lower limbs. The wrist forearm and hands are the carpal region. In total the upper limb has approximately thirty bones throughout its three segments (Saladin et al., 2021). The humerus is the main part of the bone that is connected to the scapula and the elbow. The radius and the ulna are bones that are part of the forearm, which is considered the antebrachial region. The carpal region has eight small bones that connect to five bones in the metacarpal region that is inside the palm (Saladin et al., 2021). In our body, we have a whopping 206 bones that only anatomist and doctors know. The metacarpophalangeal joints are in the middle of the metacarpal bones, and the proximal phalanges of the fingers within the hand (Saladin et al., 2021). The joints in between the proximal, middle, distal phalanges of the fingers that has no middle phalanx, is known as the interphalangeal joints (Saladin et al., 2021). The fibrous has the most flexor muscles, that is a bracelet like ligament known as the flexor retinaculum on the upper layer of the wrist (Saladin et al., 2021). The main muscle that flexes the fingers are two anterior, deep layers. Flexor digitorum profundus and flexor pollicislongus both flex the fingers and the thumbs (Saladin et al., 2021). The posterior superficial layer is an extensor digitorum that consist of stretching the muscles of the wrist and the humerus (Saladin et al., 2021). Lastly the posterior extensor compartment is another deep layer that oversees extending the thumb and index finger muscles (Saladin et al., 2021). The carpal tunnel is a tiny space within the flexor retinaculum and carpal bones (Saladin et al., 2021). The flexor tendons that go back and forth through the tunnel in a repetitive motion can deteriorate over time, which leads to carpal tunnel syndrome (Saladin et al., 2021).
Critical Thinking:
Carpal tunnel syndrome is caused when too much pressure is put on the nerves on the hand, which causes inflammation and numbness to the hands. Repetitive motion on our hands will cause them to stiff up. When our muscles begin to weaken, we must refrain from overworking them and give them a break, to prevent future damage to our body.
125 word response to…What does it mean to have the correct posture? Most people will say sitting, standing, and even while sleeping, there is a proper posture you should strive to maintain for health reasons. Most people think that muscles help with movement, but muscles play a significant part in stability. Muscles help maintain posture by preventing unwanted movement. (Saladin et al., 2020, p. 301) Some of these muscles are called antigravity muscles because they resist the pull that gravity is consistently pulling on our bodies, causing us to prevent improper posture practices. (Saladin et al., 2020, p. 301) The muscles in our joints also help stabilize joints by maintaining tension in the bones and tendons. (Saladin et al., 2020, p. 301) The isometric contraction of antagonistic muscles helps maintain stability at rest; on the other hand, the isometric contraction of postural muscles helps us from falling to the floor. (Saladin et al., 2020, p. 405)Our external obliques are one of the muscles that support the pull against gravity. It also stabilizes the vertebral column for heavy lifting, attached to ribs five through twelve. (Saladin et al., 2020, p. 321) Our Rectus abdomis stabilizes the pelvic area during walking, attached to the pubic symphysis and superior margin of the pubis. Our Multifidus stabilizes adjacent vertebrae, maintains posture, and controls movement when the erector spinae acts on the spine. These muscles are in the vertebrae C4- L5 posterior superior iliac spine. (Saladin et al., 2020, p. 324)
A study using individuals with vestibular hypofunction and individuals without impairment concluded that posture was minimally correlated with stability. (Danis et al., 1998, p. 516) Subjects moved from standing with feet apart and eyes open, transitioning to feet close and eyes closed. The subjects with vestibular hypofunction had more excellent stability than individuals without impairments in both standings. (Danis et al., 1998, p. 516) The individuals with vestibular hypofunction maintained more excellent composure by increasing trunk flexion as the sagittal distance between the shoulder and ankle and the neck and ankle increased. (Danis et al., 1998, p. 516) With feet apart, individuals with vestibular hypofunction stood with more weight on the left lower extremity, possibly causing increased body sway. (Danis et al., 1998, p. 516)
