that I am referring to are the endocrine and nervous systems. they help to regulate our bodies back to our normal state to help to maintain healthy functioning. There are two systems that work with one another to signal the brain when something is happening; they are called the controlling centers of the human body. Even though‚ these systems also work as individuals in the body. In similarity‚ the endocrine and nervous system works together as a similar function but

The Nervous System By: Brooklynne Harris Scenario A loud crashing sound causes everyone in the room to quickly turn their heads toward the source of the noise. Describe the path of the signal through the human nervous system from initial stimulus of sound to the response of turning the head. Crash and then turn of the head The Journey The loud sound that the person heard is the stimulus. In order to hear a sound‚ sound waves have to be generated and sent to the cochlea in the inner ear.

Psychology The Nervous System The nervous system is divided into two main areas‚ the peripheral nervous system and the central nervous system. The central nervous system controls the brain and spinal cord. The average human brain weighs approximately 3 pounds and contains approximately 100 billion neurons‚ as well as trillions of “support cells” called glia. The spinal cord weights approximately 35-40 grams and is around 43 cm long in adult woman and 45 cm long in adult men. The frontal

Visceral motor is directed from hypothalamus and midbrain and is involuntary‚ but has input from cortex and thalamus. Somatic lower motor neuron is in ventral horn of gray matter and neurotransmitter at skeletal muscle is Ach. Visceral motor comes from

1. Explain both the anatomical and functional divisions of the nervous system. Include the subdivisions of each. The nervous system’s function is to monitor stimuli occurring inside and outside the body‚ process and interpret this sensory input‚ and respond by activating effector organs. It consists of the Central Nervous System (brain and spinal cord)‚ and the Peripheral Nervous System (neurons that carry messages to and from the CNS). 2. Describe the composition and function of the cell

* Difference in Somatic and Autonomic Nervous System * The somatic nervous system consists of nerves that provide VOLUNTARY control over skeletal muscles * The autonomic nervous system exerts INVOLUNTARY control over the contraction of smooth muscle‚ cardiac muscle‚ and glandular activity. * Basic function of the Sympathetic VS Parasympathetic Systems * Sympathetic system= “fight of flight” * Parasympathetic system= “rest and digest” * Both autonomic branches are required
