hair and a taste pore. As you eat‚ food particles mix with saliva and enter the taste pore‚ in turn interacting with the gustatory hair. Once it is stimulated‚ the message then travels down your glossopharyngeal cranial nerve in order for you to interpret the taste. These neural impulses are transmitted through neurons and membrane potentials. Your insula then uses the gustatory cortex to interpret the sensory information from your tastebuds and you are able to determine that the burger you are eating

Margo Moriarty EDU-213 Brain Function Table Component Definition Role in Learning and Development Neurons A Neuron is a specialized nerve cell that receives‚ processes‚ and transmits information to other cells in the body. Basically‚ it is the messenger cell responsible for receiving and transmitting information. Neurons are the information processing components of the brain‚ each part of the neuron is responsible for receiving and transmitting information. Each neuron please do use role

is received‚ the neuron will then send neurotransmitters to the next neuron through the axon. After the neurotransmitters pass through the axon they are released through the terminal buttons. Then‚ the nerve impulses pass to a nerve cell at a site called the synapse. At this site‚ the impulse is transmitted to the other cell. The neurotransmitters must pass through a gap between the cells. This gap is called the synaptic cleft. Through this gap‚ the neurotransmitters are allowed to flow out of

involved 4. Osteoblasts are the specific types of cells that produce the normal microanatomy of the tissue. 5a. With ageing‚ bone mass decreases. This is espeically true of women following menopuase. Estrogen acts as a protector of bone by inhibiting the activity of osteoclasts. Once estrogen levels drop‚ after menopause‚ osteoclast activity increases. 5b. Bone mineral density (BMD) is reduced‚ bone microarchitecture is disrupted‚ and the amount and variety of non-collagenous proteins in bone

Upper motor neurons and lower motor neurons act to carry nerve impulses from the brain out to the muscles in the body. Upper motor neurons supply input to the lower motor neurons. They do this by either synapsing directly to lower motor neurons‚ or by synapsing with a local circuit neuron‚ which then synapses with a lower motor neuron. The upper motor neurons originate in the motor region of the cerebral cortex or brainstem. The neurons from the cerebral cortex are important for planning‚ initiating

1. White matter is found on the outside or surface of the cord. It connects the cord and the brain and is made up of nerve fibres. White matter contains motor fibres which run down from the motor centre of the brain‚ the cerebrum and the cerebellum to the motor cells of the cord Sensory fibres also run up the cord from the sensory cells of the cord to the sensory centre of the brain. 2.
