Antibodies are primarily<u> Y shaped proteins</u> which are <u>secreted by B lymphocytes (plasma cells specifically).</u> Antibodies are also known as immunoglobulins and provide us immunity. Apart from protein, carbohydrate is also present in antibodies. Antibodies <u>interact with antigens </u>which can be a pathogen or any other foreign molecule. The<u> interaction of antibody and antigen </u>leads to<u> antigen-antibody complex formation</u> which further leads to either <u>agglutination or precipitation reaction.</u> Due to agglutination or precipitation reaction, the <u>pathogen or foreign molecule is cleared from our body. </u>
There are <u>five types</u> of antibodies (immunoglobulins) named as <u>IgG, IgM, IgA, IgE and IgD.</u>
The answer is ganglia. As indicated, they house many cell
bodies of afferent and efferent neurons.
Spinal ganglia are located in the dorsal (that contain cell bodies of afferent
neurons) and ventral roots (that house cell body
of efferent neurons) of a spinal nerve.
Typically in mammals, the gender of an organism is determined by the sex chromosomes. In the case of humans, this happens to be the X and the Y chromosomes. So as you may recall, if you are XX, you are female. If you are XY, you are male.
