Muscular System

The teres minor is a small muscle located in the shoulder, part of the rotator cuff group. It primarily functions to externally rotate the arm at the shoulder joint and assists in stabilizing the humeral head within the glenoid cavity during arm movements. Additionally, it plays a role in adduction of the arm. Overall, the teres minor is essential for maintaining shoulder stability and facilitating upper limb mobility.

The erector spinae is a group of muscles that originates from the sacrum and the spinous processes of the lumbar and lower thoracic vertebrae. It extends upward along the vertebral column, attaching to the ribs and the spinous processes of the upper thoracic and cervical vertebrae. This muscle group plays a crucial role in maintaining posture and facilitating movement of the spine.

cuz' it's the insertion of the biceps brachi .

People used to think that a build-up of lactic acid was the cause of muscle soreness. That is not true. Lactic acid has nothing to do with it, therefore the fermentation process the body uses to get the lactic acid into the muscles is also not true. Muscle soreness is caused by the damage done to the muscle fibers. Muscle biopsies taken on the day after hard exercise show bleeding and disruption of the z-band filaments that hold muscle tissue together as they slide over each other during a contration. Scientists can tell how much muscle damage has occurred by measuring blood levels of a muscle enzyme called CPK. CPK is a normally found in muscles and is released into the bloodstream when muscles are damaged. Those exercisers who have the highest post-exercise blood levels of CPK often have the most soreness. Many people think that cooling down by exercising at a slow pace after exercising more vigorously, helps to prevent muscle soreness. It doesn't, cooling down speeds up removal of lactic acid from muscles, but a build-up of lactic acid does not cause muscle soreness, so cooling down will not prevent it. Stretching does not help either, since post-exercise soreness is not due to contracted muscle fibers.

Single-unit smooth muscle are coupled with one another through gap junctions and they work as a single unit (wave-like). I believe this is myogenic.

Multi-unit smooth muscle on the other hand, act indepently (not wave-like) and are neurogenic (stimulated by neurons). These are not coupled by jap junctions like the single-unit smooth muscle are.

There are basically two kinds of neurons- sensory and motor. Motor neurons are responsible for passing on messages from the brain, to the effector muscles, while performing a voluntary action (they also do that for involuntary actions)

Sensory neurons on the other hand, detect a stimulus, and pass on the message to the brain, which analyses the information, decides the course of action, and passes on the message back through the motor neuron, to the effector muscles.

Skeletal Muscle

A full-arc knee extension refers to the complete range of motion in which the knee joint moves from a fully flexed position to a fully extended position. This motion involves the quadriceps muscles contracting to straighten the leg, allowing for optimal knee function and stability. Achieving full-arc knee extension is important for activities like walking, running, and jumping, as it ensures proper alignment and mechanics of the lower limb. It's often a focus in rehabilitation and training to promote joint health and prevent injuries.

Muscles contract either isometrically or isotonically, and the bones provide attachment points for the muscles, one is the anchor point, the origin, and the other is the movable point, the insertion. The joint is where the two bones articulate with cartilage to produce the joint that is the lever.

It depends on your measurements. Are you talking about inches, or centimeters, and it also depends on the size and age of the person. What would be large for a 4 year old would be small for a 34 year old.

It turns out that 5400 meters or 18,000 feet is the half-pressure (500 millibars) altitude. Pressure and weight are proportional for the same gas. Don't make the mistake of thinking that doubling that gets you to the edge of the atmosphere. The atmosphere gets thinner and thinner, so the remainder of the atmosphere goes and goes and goes, with no actual boundary you can point to.

because skeletal muscle is voluntary, the autonomic nervous system is that of involuntary impulses
