#lymph node

Lymph nodes are the source of business acumen and need to be palpated and massaged regularly.

I'm getting anxious. Remember how we said May was the month of anxiety and June wasn't allowed to do that to me again? Well, June told May "Hold my beer."

I found a swollen lymph node in my neck on Wednesday afternoon. It got bigger by the time I went to bed that night. And today (Thursday) I noticed that the closest lymph node to the original swollen one has also swollen up. Thankfully it hasn't gotten as big as the original one.

According to the internet, I could just be sick. I have no other symptoms so I don't think I am. It could just be that I have a higher white blood cell count for no reason. I have no idea. But trying to research this shit on the internet is just scaring me. The medical article I read said that you should see a doctor if the swelling lasts more than two weeks. So woo freaking hoo. I might have to deal with this for a few weeks and still see a doctor.

Lymph Nodes

Lymph nodes are organs with a collagenous capsule, which are frequently found within adipose tissue.

They are strategically placed along the lymphatic network. Here they can trap foreign material (antigens), which are presented to the lymphocytes by antigen-presenting cells, to initiate an immune response.

The cortex contains primary lymphoid follicles and secondary follicles, which contain  densely packed lymphocytes. They have a distinct mantle zone and a paler-staining germinal centre.

The tissue is organised both to facilitate the interactions needed to generate an immune response against the antigen, and to promote rapid division of the responding lymphocytes.

Nodes vary in size (from a few millimetres to 1–2 cm)

Distributed in different areas of the body.

Linked in chains by lymphatic ducts, so that fluid flowing out of one lymph node via the efferent lymphatic vessel becomes the inflow to the next in line, via the afferent lymphatics.

Fluid = lymph,  derived from the tissue that carries cells and foreign material to the lymph nodes. 

Lymph returns to the bloodstream via one of the body’s two major lymphatic ducts.

Can be considered guard posts that are strategically placed to intercept any infectious agent that enters an area of the body. 

So, for example, the lymph nodes in the axilla of the arm (the armpit) will intercept infections which enter that part of the body.

Lymphocytes located in the local lymph nodes are responsible for the initial recognition of the infection and the development of the immune response. 

Once the immune response has developed, cells will migrate out from the lymph node into the blood 

move to the site of infection to combat the pathogen there.

Lymph nodes have a well defined structure with different sub-regions. 

Antigens and cells enter the node through afferent lymphatics

cells and fluid leave through the efferent lymphatic. 

Cells (lymphocytes) can also enter the node from the blood by migrating across the specialised high endothelial venules. 

Within the node, cells distribute themselves to distinct zones. 

B cells proliferate and develop within the follicles of the cortex,

T cells are primarily located in the paracortex. 

The capsule, medullary cords and hilus are fixed structural elements of the tissue.

Appendix has some major summer plans. 

@samtheappendix is going to be busy hiking and traveling the world! Hope you got some awesome plans in the works too!

You can find love in the strangest of places - even in this little bag of lymphocytes!

I think the bump on the back of my head right near my neck I mentioned yesterday is a lymph node from allergies. Hopefully not dying.

Which immune system part are you? Tonsil: reclusive and easily tamed with ice cream? Thymus: nurturing yet thinks life ends after childhood? Spleen: tough yet disposable? Or are you a Lymph Node: omnipresent and easily irritated? Share with your immunology bestie!
