SIBULO‚ MONIQUE STACY JANE B. 2012-1-1433 17 SEPTEMBER 2013 1. The function of a neuron is to convey or process signals. Discuss how the specific parts of a neuron allow this general function to occur. Neurons has four distinct zones that has each of their specialization in the transmission of signals across the body. The first zone is for signal reception‚ it consists the dendrites and the cell body. The dendrites receive the signals and be converted into electrical signals that will be

ANS? A) motor fibers that conduct nerve impulses from the CNS to skeletal muscles B) sensory neurons that convey information from somatic receptors in the head‚ body wall‚ and limbs and from receptors from the special senses of vision‚ hearing‚ taste‚ and smell to the CNS C) motor fibers that conduct nerve impulses from the CNS to smooth muscle‚ cardiac muscle‚ and glands D) sensory and motor neurons that supply the digestive tract 5) 6) An impulse from one nerve cell is communicated to

Report 2 -Karthik raj Konnaiyan Patellar reflex: Patellar reflex is contributed by 3rd and 4th Lumbar segment nerves‚ in some cases 2nd lumbar segment is also involved. So an individual will be left with patellar reflex if these lumbar vertebrae are left intact. Patellar reflex is also called knee-jerk reflex as the names implies‚ it is involved with tapping of knee at certain point will cause a jerk movement. In medical terms when an individual is tapped on patellar tendon (area below the knee

NEURONAL DIVERSITY - Categories of neurons of CNS: 1. Afferent/ sensory neurons – convey information from periphery to CNS 2. Motor- sends commands to muscles and glands 3. Interneurons – most abundant signalling elements in the CNS ( process information locally or convey information from one region of CNS to another • Types: a. Local interneurons/ internuncial neurons/ local circuit neurons – short axon Golgi type II (greatly outnumber type I in CNS)

Neuron (from the brain or spinal cord) will passed action potential through axon of motor neuron to an axon terminal. Sodium ion (Na+) and calcium ion (K+) are higher concentration outside than from the inside of the muscle and neuron. Na+ and K+ want to go inside but blocked by these channels (voltage gated

The epileptic seizures constantly reflect the abnormal hyper synchronous electrical activities of the neurons instigated by the imbalances between the brain’s excitation and inhibition. The neurons interconnect in a complicated network where every neuron is connected through the synapses with numerous others. As a result‚ small electrical currents are discharged by the neurons in a bid to discharge neurotransmitters of the synaptic degree to allow communication with one another. Numerous

The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The
