muscular and skeletal system
the function of skeletal system:
support
movement
protection
creating blood cells
different types of join and its example:
saddle joint
includes carpometacarpal join of the thumb, the sternoclavicular joint of the chest, and the incudomalleolar joint of the middle ear.
gliding joint
includes the carpal joints of the wrist, tarsal joints of the ankle, face joints of the spine.
ball and socket join
includes human hip
fixed joint
includes the joints between the bones in the skull and the joint where the radius and ulna bones meet in the lower arm
hinge join
includes ankles, elbows, fingers, knees and toes.
what is ligament and what are they for?
ligaments are bundles of connective tissue that connect one bone to an adjacent bone
ligaments keeps our bones in place and stops us from moving them too far in any direction
many of our joints have tissues between the bones to prevent rubbing, some of the example of them are:
cartilage
is strong, but smoother than bone and more flexible.
cartilage is a connective tissue found in may areas of the body including joints between the bones (ankle, knees, elbows)
synovial fluid
also called synovia, is a viscious, non-newton fluid found in the cavities of synovial joints. This acts like oil for a machine, lubricating the joints and allowing smoother movement.
what happens if there is not enough synovial fluid?
loss of this fluid, called synovial fluid results in a gradual decrease cartilage thickness and increase in friction, which is related to the degradation and joint pain of osteoarthritis. Since cartilage is porous, fluid is readily squeezed out of the holes over time.
Explain about different types of Muscle Tissues:
muscles and bones are linked by
tendons
(tendons are not elastic or stretchy, so cannot contract and relax like muscles do. But they are still flexible.)
bones are joined to other bones by
ligaments
(ligaments are very similar to tendons and you will find these in every movable joints.)
three types of muscle tissues are cardiac, smooth, skeletal.
cardiac muscle
is one of three types of vertebrate muscles, with the other two being skeletal and smooth muscles. It is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart.
smooth muscle
is a type of muscle tissue which is used by various systems to apply pressure to vessels and organs. Smooth muscle is composed of sheets or strands of smooth muscle cells.
skeletal muscle
s one of three major muscle types, the others being cardiac muscle and smooth muscle. It is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.
