The tectospinal tract connects the midbrain and the spinal cord. It is responsible for motor impulses that arise from one side of the midbrain to muscles on the opposite side of the body. The function of the tectospinal tract is to mediate reflex postural movements of the head in response to visual and auditory stimuli. Damage signs would show prevention in being able to coordinate the head‚ neck‚ and eye movements. Sensory receptors perform countless functions in our bodies including mediating vision

involving the arms and legs‚ speech‚ swallowing or breathing. When muscles no longer receive the messages from the motor neurons that they require to function‚ the muscles begin to become smaller. Therefore limbs begin to look "thinner" as muscle tissue atrophies. 4. What treatment options are available for this condition? (1 point) Drugs can be prescribed to treat the mentioned symptoms and combat further damage to the motor neurons. Baclofen could be prescribed in response to his abdominal spasticity

By Audrea Emmons Pathophysiology • Amyotrophic lateral sclerosis (ALS)‚ often referred to as "Lou Gehrig’s Disease‚" is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die‚ the ability of the brain to initiate and control

There are three major brain divisions. They are the cerebrum‚ the brainstem‚ and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions‚ such as reasoning and rationalizing‚ among

The human body has eleven main body systems. They are groups of bodily organs coming together to keep the human body going; they can perform one or more functions. The eleven body systems consist of the skeletal system‚ muscular system‚ nervous system‚ circulatory system‚ immune system‚ endocrine system‚ digestive system‚ excretory system‚ respiratory system‚ integumentary system‚ and the reproductive system. The skeletal system is the foundation to the body containing 206 bones and movable and

“NEURAL CONTROL AND CO-ORDINATION” Co-ordination - It is the process through which two or more organs interact and complement the functions of each other. Neuron - It is the functional and structural unit of nervous system. Therefore‚ the nervous system is also known as NEURAL SYSTEM. Neurons with longer projections are said to be the longest cells in our body. There are about 100 billion neurons and most of them exist in the brain. Some neurons have flask-shaped and are called Purkinje cells
