shoulder

 [shōl´der]
the area around the glenohumeral joint, the large ball-and-socket joint where the humerus joins the scapula. The smooth, rounded head of the humerus rests against the socket in the scapula. The joint is covered by a tough, flexible protective capsule and is heavily reinforced by ligaments that stretch across the joint. The ends of the bones where they meet at the joint are covered with a layer of cartilage that reduces friction and absorbs shock. A thin membrane, the synovial membrane, lines the socket and lubricates the joint with synovia. Further cushioning and lubrication are provided by fluid-filled sacs called bursae. Disorders of the shoulder include bursitis and dislocation.
Coronal section through the shoulder joint.

Patient discussion about shoulder

Q. how can i solve my back and shoulder problems? also how can i get raid of my eye bugs?

A. krando,
many thanks i will try those tips you just give me...wish you a wonderful and safe and sound newly year...

Q. shoulder and neck strain and pain I have a terrible shoulder and neck pain and i keep cracking my neck muscles to release pressure. I get temporary relief with tylenol but after few hrs the pain and strain starts again.Any ideas?

A. A mellow exercise and streching on a regular basis is the best way to release a sore back and muscles in general, including your neck. You should try that plus applying local warm temperature (for example a warm pillow)around your neck. If that doesn't work then other anti-inflammatory drugs that you either apply as a cream or take as a pill can help you.

Q. How do I gain range of motion after shoulder surgery I'm 31 years old and had a shoulder replacment last year. I still don't know why my joint gave out and 4 Orthopedic Surgeons couldn't tell me either. I have limited Range of Motion and the Dr. seems to think that because of my "age" I was less likley to get full range back. I refuse to believe that, does anyone have any suggestions on how to gain ROM back?

A. i guess you go to physiotherapy no?
that is their job. to give you range of motion after injuries, surgeries ect. they'll give you exercises specially for your condition. when i had an accident i broke my leg hip and i needed 2 months of physiotherapy that helped very much.

The shoulder is in the same location for the two cases but the .33 Nosier has a sharper shoulder angle so the neck/shoulder junction sits closer to the case head.

He developed the "improved" cartridge concept whereby a commercial cartridge's case taper and shoulder angle are improved in order to increase case capacity, resulting in more efficient powder utilization, higher velocity, and higher energy.
The .257 Roberts was developed by and named for experimenter Ned Roberts in the 1920s, who necked down the 7x57 Mauser case down to .25 caliber, and changed the shoulder angle to 15 degrees.
With a case length of 2.170 inches, shoulder diameter of .475-inch and shoulder angle of 35 degrees, it holds considerably more propellant than the .308 and kin.
The case shoulder was pushed forward about 0.075 inch, and the shoulder angle was increased from 23 degrees to 30 degrees.
The basic cases are very modern in appearance having a minimum body taper and a sharp, 23-degree shoulder angle (the .308 Win shoulder angle is only 20 degrees).
The head-to-shoulder and neck lengths differ minutely as well, though the .280's shoulder angle is the same as the .30-06: 17 1/2 degrees.
The problem here seems to be that the shoulder angle is so sharp that it cannot properly support the neck against the thrust of bullet-seating.
In its commercial incarnation, the .22-250 shares almost every dimension with its wildcat parent except for an almost imperceptible 1.5-degree difference in shoulder angle. It is an elegantly simple conversion.
Cartridge guys obsess over things like shoulder angle, case neck length, primer pockets, flash holes, belts or no belts.
