Which of the following describes the pathway that the nerve impulses travel while throwing a baseball
Im thinking its Sensory neuron to brain to motor neuron to muscle
To understand the pathway that nerve impulses travel while throwing a baseball, we need to consider the key muscles and nerves involved in the throwing motion.
1. The brain: The process begins in the brain, specifically in the motor cortex. This is where the decision to throw a baseball is made.
2. Motor nerves: The motor cortex sends signals through a network of motor nerves, which carry the nerve impulses from the brain to the relevant muscles. The motor nerves involved primarily originate from the spinal cord.
3. Spinal cord: The spinal cord acts as a crucial relay station for transmitting nerve impulses between the brain and the muscles. When the brain decides to throw a baseball, the motor neurons in the spinal cord are activated.
4. Shoulder muscles: Once the nerve impulses reach the shoulder, they stimulate the contraction of various muscles involved in throwing, such as the deltoids, rotator cuff muscles, and trapezius. These muscles work together to produce shoulder movement and generate the necessary force for throwing the baseball.
5. Arm muscles: The nerve impulses then continue down the arm, activating muscles such as the biceps and triceps. Contraction of these muscles helps in the extension and flexion of the elbow joint, critical for the throwing motion.
6. Hand and finger muscles: Finally, the nerve impulses reach the muscles in the hand and fingers, responsible for releasing the baseball. These muscles include the flexor and extensor muscles of the fingers and wrist.
It's important to note that this is a simplified explanation of the pathway, and there are more intricate details and complexity involved in the actual neural processes.
