Muscular System
By: Ricardo Hernandez P.2
3 Types of the Muscular System and their Functions
Skeletal
Skeletal tissue are muscles that are attached to bones and helps your body to move and do your daily activities in life.
Voluntary meaning you can improve your skeletal muscles by exercising to make them better than before
Smooth
Involuntary muscles and non striated muscles
It is a wall of hallow organs that helps them to be stronger for an example your intestines and you liver are parts of the smooth muscle
Cardiac
Only found in the heart
This muscle can help your heart pump blood
Involuntary
All of the skeletal muscles including the facial muscles
Here is a list of all of them
Upper Half
trapezius
sternocleidomastoid
deltoid
pectoralismajor
serratus anterior
bicep brachii
tricepbrachii
brachioradialis
flexor carpi radialis
rectus abdominis
external oblique
infraspinatus
teres major
latissimus dorsi
extensor carpi radialis
flexor carpi ulnaris
extensor digitorum
rhomboid major
Lower Half
iliopsoas
adductor longus
sartorius
gracilis
rectus femoris
vastus lateralis
vastus medialis
bicep femoris
semitendinosus
semimembranosus
tibialis anterior
extensor digitorum longus
fibularis longus
gastrocnemius
soleus
gluteus maximus
alcaneal (achilles)
Facial Muscles
Corrugator supercili Orbicularis oculi Levator labil superloris zygomaticus minor and major Buccinator Risoris Orbicularis Oris Mentails Platysma Masseter Sternocleidomastoid Trapezius Splenius capitis
Sacrcomere
Actin
The think filament and also is connected to the Myosin
Myosin
The thick filament and is also connected to the Actin
Muscle fibers
M band
H band
I band
A band
Sacrcoplasm Reticulum
Nueromuscular junction
Motor end plate
It channels long protein molecules and runs through the membrane
Muscle fibers
Actin
Myosin
Action potential in a muscle fiber
This is where the neuromuscular junction takes place and sends a message to the muscles and creating a way to move the muscles.
Sliding Filament theory
Myosin filaments contribute energy from ATP and make it move to the actin filament to the cross bridge, a way to transmit energy. This also moves the Z line closer and giving the sarcomere.
