somebody's toes did not a-pop

I kid I kid....sorta!
Apoptosis- A process of programmed cell death

I was reading in my textbook and got to the section on cell structures and their functions. Then I got distracted and geeked out about lysosomes for going on 5 days now! Lysosomes are organelles that clean up cellular debris and anything else that needs to be disposed of. They also play a role in the apoptosis that happens during fetal development of fingers and toes. A lack of lysosomal activity can lead to syndactly which is "webbed toes" or fingers.
I totally geeked out because my fantastical boyfriend has webbed toes! I started to wonder if he lacked lysosome activity in-between his toes...does he lack lysosome activity elsewhere? Could that even be dangerous...
So a googling I went! I found out that syndactly is included in syndromes of many genetic diseases! It can also be a result of familial inheritance. 
My man is healthy and for sure inherited his webbed toes from a family member who shall remain unnamed ;)
 However other types of lysosomal dysfunction can have devastating effects when they happen! One example of a lysosomal storage disease is Tay-Sachs disease, which is a result of lysosomes lacking a specific lipid digesting enzyme. This causes a buildup of this lipid in cells, especially in the cells of the nervous system. It leads to progressive neurodegeneration and eventual death in infants and young children. So lysosomes are quite important and have a role in many crucial cell processes! So far they are my favorite organelle!

My man is quite proud of his toes, and I think they are super cool too! My 8 year old was convinced we were trying to trick her when he showed them too her. She insisted he had glued them together! It was hilarious!

A learning journal....

My A&P instructor has assigned us a writing assignment for our semester. I could either write a term paper with references and all that official jazz or keep a learning journal. Easy choice!
 I like blogging I have done it before and I love the subject material and I think it will be fun to analyze it and then share how I think and feel about it here.
So for starters we have been reviewing things we are already supposed to know, based on our pre-reqs for this class. I am at a loss as far as chemistry goes but I do have my genius boyfriend helping there. As far as other basics go, thank goodness for Bio 106 (as limited as it was) and my prior insane interest in the subject. Its not hard for me to remember things I love to know about!
I have been practicing the regions of the abdominopelvic area by tickling them out on my chosen toddler subject. As I am tickling her I call out exactly what I am tickling....The umbilical and illiac regions seem to be the hardest for her to maintain anatomical position in but that's to be expected I suppose : )
