The structure and mechanics of the locomotor system
BONE FORMATION PROCESS
the process of bone formation from directly converted (undifferentiated) mesenchymal tissue
Endochoral ossification begins with mesenchymal cells that differentiate into cartilage cells (chondroblasts).
Muscle Building Structure
called the sarkolemma or plasmalemma
called Srkoplasmic Reticulum
Energy for Muscle Contraction
The most readily available source of energy for muscle contraction is adenosine triphosphate, abbreviated as ATP. Furthermore, ATP is a source of energy contained in muscle fibers as a source of sudden energy for muscle contraction.
Sympathetic & Parasymphatetic
is the nerve that controls homeostasis and the body at rest and is responsible for the "rest and digest" function of the body
controls the body's response to perceived threat and is responsible for the "fight or flight" response
Conctraction and Relaxation Muscle
is a state when the muscles tighten and shorten so that they can then move the bones or skeleton of the body
The mechanism of muscle contraction starts from the central nervous system as the body's control center. The central nervous system, both the brain and spinal cord fire impulses or action potentials to motor neurons. The action potential then propagates to the ends of the muscle fibers triggering the release of acetylcholine.
is a condition when the muscles are stretched again
f there is a lot of ATP in myosin, then it can contract. Conversely, when ATP is reduced, the muscles will slowly stop contracting and return to their normal or elongated (relaxed) state. The second cause is a signal or impulse.
The Structure and mechanism of the locomotor system
function as an active locomotor
types of muscle
Myositis (including polymyositis amd dermatomyositis
consists of 12 pairs of cranial nerves and 31 pairs of cranial nerves spinal.
These nerves are composed only of sensory fibres, but are mostly composed of sensory and motor fibres.
combined motor and sensory nerves, carry information to the cord via afferent neurons and leave via efferent.
Types Of Bone
example : The Femur
example : The wrist bones
example : the shoulder bone
example : The Jawbone
