The nervous system is two parts:
– the central nervous system (CNS) and
The CNS includes the brain and the spinal cord.
Which are responsible for processing and relaying information throughout the body.
The brain is the body’s control center.
Responsible for conscious and unconscious functions such :
– movement,
-sensation,
-thought and
-emotion.
The spinal cord is a long bundle of neurons that runs from the brainstem down to the lower back.
It serves as a channel for transmitting signals between the brain and the rest of the body.
The PNS includes all of the nerves that branch off from the spinal cord and extend throughout the body.
It can be divided into two categories:
– the somatic nervous system
The somatic nervous system controls voluntary movements.
Moving your limbs.
The autonomic nervous system controls involuntary movements.
As the beating of your heart or the dilation of your pupils.
LOGICAL THINKING
The central nervous system plays a crucial role in logical thinking.
It is responsible for receiving, processing and analyzing information.
Used to make decisions and problem-solve.
Logical thinking involves the ability to reason accurately and objectively based on available evidence, weigh the pros and cons of different actions, and understand cause-and-effect relationships.
The CNS is up of the brain.
Which controls cognitive functions as attention, memory, perception, and reasoning.
The spinal cord is a key component of the central nervous system .
It sends and receives information between the brain and the rest of the body.
Research has shown that damage to certain areas of the brain can lead to impairments in logical thinking.
Lesions in the prefrontal cortex can result in difficulty with decision-making and problem-solving.
The central nervous system is essential for logical thinking.
It allows us to process and analyze information.
Reason and make decisions based on that information.
The speed at which thoughts spread throughout the central nervous system varies depending on several factors.
At which electrical signals travel down nerves can range from about 1 meter per second to over 100 meters per second.
The speed of thought depends on the type of neuron involved.
Some neurons are myelinated, meaning they have a fatty substance called myelin wrapped around them.
Allows electrical impulses to travel faster.
The distance over which the thought spreads can affect its speed.
The speed of thought spread in the central nervous system is highly complex and can vary depending on many factors, including the type of neuron, the presence of myelin.
The distance over which the thought needs to travel.
The speed of movements generated by the central nervous system varies.
Depending on several factors, including the type of movement, the target muscles, sensitivity of the reflexes, and the individual’s level of physical fitness and health.
The movements that are associated with reflexes, as the quick withdrawal of a limb .
It comes into contact with a harmful stimulus, can happen within a fraction of a second.
These movements do not need conscious thought.
They are generated by a neural circuit that bypasses the brain’s cortex, which is responsible for conscious decision-making and planning.
Movements that require conscious thought.
As voluntarily lifting an object, can take longer to initiate.
These movements require the brain to interpret sensory information.
Formulate a plan of action sending signals through the nervous system to the target muscles.
The speed of these movements can depend on the individual’s level of training and experience.
Movements that require coordination between multiple muscle groups, as those involved in balance and posture.
Can take longer to initiate and require more feedback from sensory systems to ensure movement accuracy.
The speed of movements generated by the central nervous system is highly variable and depends on factors as the type of movement.
The muscles involved, reflex sensitivity, and the individual’s level of fitness and training.
Physical work and fitness movements are both types of physical activity.
They differ in their underlying mechanisms and purposes.
Physical work refers to activities performed for utilitarian purposes, as lifting, carrying, pushing, or pulling objects.
Fitness movements are used for exercise and enhancing physical fitness, as running, jumping, or lifting weights.
One of the main differences between physical work and fitness movements is the level of conscious control involved.
Physical work is often performed reflexively or habitually, without much conscious attention or input from the central nervous system (CNS).
The CNS simply activates the appropriate motor neurons and muscle fibers to perform the task efficiently and safely.
Fitness movements are typically deliberate.
Goal-directed actions that require conscious planning, monitoring, and adjustment of movement patterns.
Physical work and fitness movements differ in their energy demands and metabolic responses.
Physical work is often characterized by brief.
Intense bursts of muscular activity requiring primarily anaerobic metabolism and producing high levels of fatigue and muscle damage.
Fitness movements,involve longer-duration, moderate-intensity efforts that rely on aerobic metabolism and produce less muscle damage and fatigue.
Physical work and fitness movements are two distinct types of physical activity with different mechanisms, goals, and outcomes.
Physical work is often reflexive and utilitarian.
Fitness movements are deliberate and designed to enhance physical fitness.
The central nervous system (CNS), which includes the brain and spinal cord.
Plays a crucial role in regulating and controlling movement exercise.
The CNS receives sensory information from the body and sends motor commands to the muscles through nerve impulses.
This allows for coordinated movement and optimal performance exercise.
The CNS regulates the cardiovascular and respiratory systems.
Are essential for endurance and aerobic capacity exercise.
The CNS plays a role in motivation, influences an individual’s willingness to engage in physical activity and continue to improve their fitness level.
The CNS is integral to the body’s ability to improve physical fitness through exercise.
The central nervous system plays a crucial role in physical fitness by controlling and coordinating all the body’s movements and functions.
It receives and processes sensory information from the environment.
Integrates this information with motor commands.
Triggers the appropriate responses from the muscles and organs.
This coordination and control allow individuals to perform physical activities.
That improve their fitness levels, as cardiorespiratory endurance, muscular strength, and flexibility.
The central nervous system modulates physiological responses to exercise, as heart rate and blood pressure.
To maintain homeostasis and optimize performance.
Fitness, which includes regular exercise and physical activity, has a significant impact on the nervous system.
Exercise stimulates the growth and strengthening of nerve cells in the brain and spinal cord.
This process, called neuroplasticity, helps to improve cognitive function, memory, and learning abilities.
Physical activity, the nervous system sends signals to the muscles to contract and relax.
Resulting in improved coordination, balance, and agility.
Regular exercise has a positive effect on the autonomic nervous system.
Which controls involuntary bodily functions as heart rate and breathing.
Exercise can help to reduce stress and anxiety, lower blood pressure, and improve cardiovascular health.
Exercise has been shown to promote the release of neurotrophic factors.
Which are proteins that support the growth and survival of neurons.
These factors help to protect the nervous system from damage and degeneration caused by aging, injury, and disease.
Fitness plays a critical role in maintaining a healthy nervous system.
Improving mental and physical well-being, and reducing the risk of developing neurological disorders.
To maintain good nervous system health.
It is recommended to engage in at 30 minutes.
Of moderate-intensity aerobic exercise, as brisk walking, jogging, or cycling,most days of the week.
Engaging in regular physical activity can help to improve cognitive function.
Promote better sleep, and reduce stress and anxiety levels.
The amount of exercise needed may vary depending on individual health factors and fitness goals.
It’s always best to check with a healthcare professional starting a new exercise program.
Maintaining a healthy nervous system is crucial for our health and well-being as it governs all the functions of the body.
Here are some healthy combinations that can be made daily for the nervous system:
1. Omega-3 fatty acids and Vitamin B12:
- Consuming foods rich in Omega-3 fatty acids and Vitamin B12, as fatty fish, nuts, seeds, and leafy greens, can support the nervous system’s function and improve brain health.
2. Antioxidants and amino acids:
- Antioxidants like berries, dark chocolate, and green tea paired with amino acids as tryptophan found in turkey, chicken, and oats can help reduce stress and anxiety and improve mood.
3. Magnesium and calcium:
