The MicroscopeMaster website is for educational purposes only. - Lignin builds up in the cell wall in spiral rings increasing the strength of the xylem allowing them to withstand the water pressure. The main portion of the neuron is the cell body. While it lacks many of the organelles found in the cell body, the axon contains microtubules (along the length of the axon) and specialized, insulating substances known as myelin on its surface that boost the transmission of nerve impulses. - These are the type of neurons that connect the motor neurons to the sensory neurons thus allowing for signals to be transmitted between the two. 30 seconds . Muscle cell: Fibres which can contract making the cell get shorter. This type of cell sends messages throughout the body in the form of electrical impuses. Motor neurons are composed of multipolar neurons. Dendrites extend from the cell body to make connections with other neurones. In adults, stem cells are specialized to replace cells that are worn out in the bone marrow, brain, heart and blood. Q. Nerve endings (synapses) are adapted to pass the impulses to another cell … The embryo grows, and eventually the cells become more specialised. For the most part, it involves the summing up of excitatory and inhibitory responses (this being integration of incoming signals) in order to determine whether certain information should be transmitted. The MicroscopeMaster website is for educational purposes only. Download the Cell Specialisation Worksheet. It also provides structure and support to the plant. These specialized nervous system cells are called neurosecretory cells, and they produce neurosecretions. Some people call it specialisation, some specialization. Like motor neurons, this system is composed of multipolar neurons. Cell Specialisation; Red blood cell : Contains haemoglobin to carry oxygen. Edit. When a cell is modified from the general structure – parts removed or added. - The integrative function occurs in the dendrites (receptive components) as well as the cell body of the neuron.
