neuron structure synapse

The junction between the axon and the dendrites of the next neuron is called the synapse . At the synapse, the axon fibres and dendrites are not in direct contact. The space between them is called synaptic cleft . Within the axons are synaptic vesicles having chemic..

The junction between the axon and the dendrites of the next neuron is called the synapse. The end of the axon is branched into many fibres that are devoid of the myelin sheath. At the synapse, the axon fibres and dendrites are not in direct contact. The space between t..

. Axons with such a covering are called as myelinated or medullated and those without are called as non-myelinated or non-medullated. The function of myelin sheath is to increase the speed of conduction of the impulse. There is another cellular covering surrounding the axon, called neurilemma (or s..

Question 21 - Question: What is a synapse? Answer: The junction between the axon and the dendrites of the next neuron is called the synapse..

Based on their structure and function, the neurons are classified into three typ..

Types of Neurons - Based on their structure and function, the neurons are classified into three typ..

Each macula has a set of sensory hair cells embedded in a gelatinous mass. At one end the tuft of hairs can come in contact with calcareous ear stones or otoliths, that are embedded in the gelatinous layer. At the other end, the cells synapse with the neurones of the vestib..

Structure of Cell - Cells vary in shape and size. They may be oval, spherical, rectangular, polygonal, spindle shaped, star shaped, rod-shaped or totally irregular like the nerve cell. The diversity in cells is in accordance with the role or function it has to perform as part of the tissu..

The axons of the motor nerve fibre end on a muscle fibre or a gland. The synapse formed at the junction of the motor nerve fibre and the muscle fibre is called the neuromuscular junction. At the neuromuscular junction also, the axon forms branches that are devoid of myelin sheath. At the ..

It comprises of the nerve cells or the neurons. These nerve cells are bipolar. One end of the bipolar cells, synapses with the rods and cones and the other end synapses with the ganglions present in the next layer. There are certain nerve cells called the horizontal a..
