Neuron in the Dorsal Root Ganglion
In the peripheral nervous system, cell bodies of neurons are organized as ganglion. An example would be the Dorsal Root Ganglion that is found in the posterior nerve roots of the spinal cord. The neurons found in it are classified … Continue reading Neuron in the Dorsal Root Ganglion
Neuron
Neurons as a cell type have very diverse structures. They could be classified by their modalities and morphologies. Their functions are to conduct messages to and from the Central Nervous System and Peripheral Nervous System, or within each system.\ Continue reading Neuron
Pacinian Corpuscle
Pacinian corpusles are structures that can be found in the dermis. They are the encapsulated end of a sensory neuron that detects vibration and pressure. The corpuscle resembles a flattened plate. Continue reading Pacinian Corpuscle
Motor Endplate
Motor endplate is also known as terminal button. This is the specialized synapse that an alpha-motorneuron makes to all the muscle fibers (i.e. a motorunit) it innervates. Acetylcholine is secreted at the synapse that in turn depolarize the muscle fibers … Continue reading Motor Endplate
Muscle Spindle
Muscle spindle is a stretch receptor that is found within the belly of a muscle. It monitors how stretched that particular muscle is and initiate the stretch reflex to prevent injury caused by over-stretching and to maintain posture. Below is … Continue reading Muscle Spindle
Pia Mater
Pia mater is the innermost layer of the meninges, clinging tightly to the brain with all the sulcus and fissure. It is composed of a thin layer of simple squamous epithelial cell and areolar tissue. It is further invested with … Continue reading Pia Mater
