1. Brainstem- It begins where the spinal cord swells after entering the skull. It regulates all automatic survival roles‚ such as breathing and heartbeats. 2. Thalamus- The thalamus is the uppermost part of the brainstem. It directs information to the sensory cortex and provides feedback to the cerebellum and medulla. 3. Medulla- The foundation of the brainstem. It manages heartbeat and breathing. 4. Reticular formation- The nerve region travelling through the brainstem and thalamus. The network

As I was waI stopped to take a breather as I was done finishing my last lap out of the 4 miles. I had called my mom to pick me up and ten minutes ago‚ but she was not here yet‚ I just assumed she was just running a little bit late. I can tell you standing outside in the flaming fiery sun‚ covered in sweat with no water bottle in hand is no fun. As I was waiting beads of sweat‚ thermoregulatory sweating‚ started appearing on my skin. The two types of sweating are eccrine glands‚ armpits‚ and apocrine

The nervous system is made up of millions of neurons and interconnected nerves that are comparable to a wiring system. The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The nervous system functions like a corporate giant. The CEO is the leader in the CNS and the officers and delegates are the PNS. The CNS gives the commands and the PNS follows the commands. The Central Nervous System The central nervous system (CNS) is

Neurogenic Shock Neurogenic shock is a type of shock that is caused by a spinal cord injury that affects important nerves in the nervous system. Injury to the nervous system causes the walls of blood vessels to relax‚ which increases the blood pressure. Neurogenic shock mainly affects the spinal cord. The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. Neurogenic shock occurs when a spinal cord injury happens‚ particularly involving

B1: The permeability of the cell increases enormously during the action potential. Comte Whitney Electricity is vital for neural function and communication. The semi-permeable membrane and presence of charged particles in solution (ions)‚ enables the cell to have control of an electric potential. The cell The concentrations of Na+ and K+ ions upon either side of a cell’s membrane are not equal. In order for the equilibrium to be restored‚ sodium will attempt to enter the cell‚ whilst potassium will

In this paper‚ I will be discussing the normal physiology of the basal ganglia‚ or basal nuclei‚ how the different structures within are involved with motor functions‚ and how dysfunctions within the basal ganglia lead to movement disorders. The basal ganglia are a group of interconnected subcortical structures composed primarily of the striatum‚ pallidum‚ substantia nigra‚ and the subthalamic nucleus. These structures span across the diencephalon‚ telencephalon‚ and the midbrain‚ and lie under

Synaptic Cleft Structure and Function Elizabeth Moreno Biochemistry at TMI Abstract A synaptic cleft is the space between neurons at a nerve synapse across which a nerve impulse is transmitted by a neurotransmitter—called also synaptic gap (Merriam-Webster) . This paper will utilize this simple definition in order to understand the synaptic cleft. Furthermore‚ we will explore the complex functions and the structure of the synaptic cleft. This will then allow for an in depth analysis

Abstract: The purpose of this experiment was to examine how the compound action potentials propagate down the sciatic nerve of a frog based on varying stimuli. Before the nerve could be tested it needed to be extracted from the thigh of the frog and then submerged in saline. Several varying stimuli were used and recorded by a software package. The second experiment requires a constant stimulus with varying reference pin locations. From this the velocity of the action potential propagated can be

Reflexes Laboratory Activity (12 points) 1. Amy has numbness of her pinky‚ ring finger‚ and medial surface of her right arm. After neurological testing‚ it is determined that she has a compressed spinal nerve on the right side. a. Which spinal nerve (what level) is affected? The level is C5-T1 cervical nerves. The specific spinal nerve would belong to the brachial plexus‚ the ulnar nerve. b. How did you determine/decide it was this level? The ulnar nerve branches off of the medial cord‚ which is
