MUSCLE CONTRACTION-MECHANICS-BIOMECHANICS NOTES

Muscles Are Organized Into Motor Units

  • When a single nerve enters a muscle it splits and makes neuromuscular junctions (NMJs) with several muscle cells
  • A nerve and the muscle cells it makes NMJs with is called a motor unit
  • When the nerve fires the whole motor unit is stimulated and the muscle cells contract together
  • Muscles with large motor units have coarse movements
  • Muscles with small motor units give fine, graded movements
  • This is a small motor unit with only 3 muscle fibersTwo Basic Types of Contraction Are Isotonic and Isometric

FUTURE OF BIOMEDICAL ENGINEERING IN INDIA PERTAINING BRAIN DRAIN

As we know today in India we think that only those branches of engineering are important which are job oriented and others have no meaning for us.This has acted like a sabotage for the development of biomedical in the country

We can see easily that today people prefer to go outside the country after doing biomedical engineering for the purpose of post-graduation so that they can secure a good job there as in the world of developed nations people of our country are ready to mould themselves according to the circumstances present there. I personally feel that brain drain of biomedical engineers to west is taking place because of the lack of resources in our country and laziness of our leaders as well as students for the promotion of the resources  available in the country

Brain scans reveal what's in your mind's eye

Brain scans reveal what's in your mind's eye

Scientists are getting closer to being able to create an image of whatever you’re picturing your mind. This is either completely amazing or absolutely terrifying. Maybe a little bit of both.

To construct their model, the researchers used an fMRI machine, which measures blood flow through the brain, to track neural activity in three people as they looked at pictures of everyday settings and objects.As in the earlier study, they looked at parts of the brain linked to the shape of objects. Unlike before, they looked at regions whose activity correlates with general classifications, such as “buildings” or “small groups of people.”

This is no phone; it's an ultrasound machine

This is the GE VScan portable ultrasound machine. Yes, it looks almost exactly like a flip phone, but you can’t make any calls on it.

Instead, it’s designed to make giving ultrasounds cheaper and easier, reducing the number of referrals and improving diagnoses. Because more doctors will be able to have these things, they’ll be able to use them instead of sending patients elsewhere. Also, they can carry one in their purse in case they really need to do an ultrasound on the go, which I’m sure will come in handy.

LifeHand restores touch using thought-controlled robotics

Bringing to mind images of Luke Skywalker’s robotic hand in the film Star Wars, an Italian team recently achieved a prosthetics breakthrough that mirrors science fiction. Neurologist Paolo Maria Rossini led a team at Rome’s Campus Bio-Medico, to create a robotic hand that allows the wearer to control the hand with thoughts and feel sensations through the device.

Funded by the European Union to the tune of $3 million, the project marks the first time an amputee has been able to make truly complex movements using a robotic prosthetic. Called the LifeHand, the project is just the beginning as another E.U. initiative called the SmartHand hopes to replace an entire human arm.
