What are some symptoms of spastic cerebral palsy?
Some symptoms of spastic cerebral palsy are muscle stiffness, uncontrolled movements, and problems with posture. It can, also impair other functions such as coordination, balance, speech, and swallowing.
How does tonic contraction help maintain posture?
Tonic contraction holds the muscles in position. In other words, muscle tone maintains posture.
A contraction in which a skeletal muscle does not shorten but its tension increases is called isometric?
An isometric contraction is the name given to a skeletal muscle that does not shorten, but increases tension. The muscles generate force to protect themselves.
What is the result of bilateral contraction of the erector spinae group?
Bilateral contraction of the erector spinae group results in extension of the spine, helping to maintain an erect posture and stabilize the vertebral column during activities like standing and lifting.
An imbalance caused by contraction of pectoralis minor would result in what type of body position. what opposing muscles might be affected by this contraction?
An imbalance caused by contraction of the pectoralis minor muscle can result in a rounded shoulder position known as forward shoulder posture or kyphosis. Opposing muscles that might be affected by this contraction include the rhomboids and lower trapezius, which become lengthened and weakened, contributing to the postural imbalance.
What constant slight contraction on certain fibers in a muscle?
The constant slight contraction of certain fibers in a muscle is known as "tonus" or muscle tone. This state of partial contraction helps maintain posture and readiness for movement, providing stability to the body. Muscle tone is regulated by the nervous system and involves a balance between excitation and inhibition of motor neurons. It is essential for overall muscle function and coordination.
How can speed effect posture alignment and intensity?
Speed can negatively impact posture alignment when movements are fast and uncontrolled, leading to poor body mechanics and increased risk of injury. On the other hand, performing exercises at a slower, controlled pace can improve posture alignment by allowing for proper engagement of muscles and joint stability. Higher speed can also increase exercise intensity by challenging cardiovascular endurance and muscle power, but proper form should always be prioritized to prevent injury.
Some muscle fibers always contracted?
Summation and/or tetanic contraction. Summation is increased muscle contraction until maximal sustained contraction is achieved. Tetanic contraction is sustained muscle contraction without relaxation. If you're inquiring for the Learning Objective Review in an anatomy and physiology course, the question refers to a condition in which some fibers are always contracted... so I'm not sure if they're looking for summation or tetanic contraction - but I think it would be tetanic contraction as summation is more the process leading up to the tetanic contraction...
What Major function is to contract?
The major function of a muscle is to contract and generate force, which allows for movement, stability, and posture in the body. This contraction occurs when muscle fibers shorten and produce tension.
Types of posture?
Kyphosis Lordisis Flat Back posture Sway Back posture Scoliotic posture Hope it helped :)

Which results from a degeneration of dopamine-releasing neurons of the substantia nigra and leads to symptoms such as persistent tremors at rest forward-bent walking posture and shuffling gate?
Parkinson's disease is the degeneration of dopamine-releasing neurons in the substantia nigra. Symptoms include persistent tremors at rest, forward-bent walking posture, and a shuffling gait due to decreased dopamine levels in the brain.
