Noah Lopez P.1 Anatomy and Physiology Muscular System
Major Functions
Help generate heat
Allow for our bodies to move, like lifting, walking, running, etc..
keeps out posture and allows us to stand straight up
Skeletal Muscles
Lower body Front: Liopasoas, sartious, Adductor longus, Linguinal Ligament, Rectus femoris, Vastus lateralis, Vastus medialis, Gastronemius, Soleus, Tibialis anterior, Fibularis Longus, Soleus,
Upper body front: Sternohyoid, Trapezius, Deltoid, Pectoralis major, Biceps Branchii, Brachioradialis, Rectus Abdominis, Flexor Carpi Radalis
Facial: Temparalis, Frontails, Orbicularis oculi, Masseter, Platysma, Zygomaticus, Orbicularis Oris
Upper body back: Deltoid, Steronlecidomadstoid, Trapezius, Infrapinators, Rhomboid minor, Triceps branchii, Latssimusi dorsi, Extensor carpi, radialis longus
Lower body back: Gluteus Maximus, Hamstring, Semiendinous, Semimem branousus, Gastricnemius, Soleus, Fibularis longus, Achillies tendon
The Sarcomere
Is found within the ends of myofibril
Allows and where muscle contraction takes place
contains ATP, Myosin, and Actin
Contain Z discs, I band, A band, H zone, and M line
Three types of Muscles
Skeletal Muscle
muscle attached to bones with tendons. Enables voluntary movement/control
Smooth Muscle
Lines many of the internal organs, giving shape and protection
Cardiac Muscle
Specfific only to heart, It protects it by lining the walls.
Neuromuscular junction
AP arrives to the axon terminal, allowing for calcium to enter the internal motor neuron
When calcium enters, ACH is able to be released
ACH binds to receptors and is eventually broken down by Acetylcholine
Disorders
Duchenne Muscular dystrophy: A muscle destorying disease, that occurs in childhood. A lack of dystrophin is a big reason for why this disease occurs. It is very common
Myasthenia gravis: A disorder that causes for the muscles to stop having a neurological connection. Voluntary movement is hard and this occurs with age.
Sliding Filament theory
: 1. Brain sends signal to neuron in muscle with neuromuscular junction. Atichloyne is realsead.
2: The signal travels through to the T tubules , into the sarcoplasm reticulam. Calcium is stored there and it releases
3: The signal stops and Calcium along with Sodium stop.
The myosin from the sarcolemma is disconnected with ATP. The heads detach and the muscle relaxes
