The study of muscles
Myology
What is the purpose of the muscles?
Enable movement, support the body, maintain posture, produce body heat
Away from the body
Abduction
Toward the body
Adduction
Tendon of the gastrocnemius that inserts at the tarsus and hock
Achilles tendon
Antagonists
A muscle acting in opposition to another
Broad sheet of connective tissue that serves as a tension to attach muscles to bone or bind muscles together
Aponeurosis
Apo- meaning derived from, and neur/o- meaning nerves
Involuntary (smooth) muscles that raise the hairs on the back
Arrector pili
Biceps brachii
Flexor of the distal foreleg
Flexor of the distal hind limb
Biceps femoris
Type of striated muscle fiber found in the heart
Cardiac
Muscle found in the spermatic cord that raises and lowers the testicles
Cremaster
Muscle of the dermis responsible for insect- repelling skin twitch
Cutaneous trunci
Diaphragm
Wall between abdominal and thoracic cavities
Epaxial group
Muscles of the dorsal back. Sometimes used for IM injections
Muscles that extend a part of the body
Extensors
Respiratory muscles between the ribs
External intercostals
Muscle that compresses and supports the abdomen
External oblique
Kind of reminds me of an accordion contracting and relaxing from the sides
Fibrous membrane that encloses the muscles and separates them into groups
Fascia
Fibers
Muscle threads or filaments. Usually in bundles
Muscles that flex a part of the body
Flexors
Gastrocnemius
Muscle of the distal hind limb that flexes the leg and extends the foot
(Calf)
Group of muscles on the dorsal pelvis. Sometimes used for IM injections
Gluteal group
The more movable of the 2 points of attachment of a muscle
Insertion
Respiratory muscles situated between the ribs
Internal intercostals
Muscle that compresses and supports the abdomen
Internal oblique
The broadest muscle of the back
Latissimus dorsi
Connects bone to cartilage
Ligament
Carti L age, L igament
Connects bone to bone
Ligament
Center attachment of abdominal muscles on the ventral walls
Linea alba
Muscle of mastication (chewing)
Masseter
Looks like mass-eater
The nerve that connects to a muscle
Motor nerve
Neuromotor unit
A combination of the nerve cell and its group of muscles that are stimulated to cause muscle contractions
Muscle of the eyelids
Obicularis oculi
The less movable of 2 points of attachment of a muscle
Origin
Group of muscles in chest. Sometimes used for IM injections
Pectoral group
Muscles that actively produce a movement/ are mostly responsible for a movement
Prime movers
Like the protagonists to the antagonists
Quadriceps femoris group
Group of muscles important for extension of the hind limb
Sarcolemma
Plasma membrane of the muscle cells
Cytoplasm of the muscle cells
Sarcoplasm
Flexors of the distal hind limb
Semi group (hamstring group)
Group of muscles important for supporting the trunk
Serratus group
Striated, voluntary muscle
Skeletal
Non- striated, involuntary muscle
Smooth
Muscles that work together to aid the prime movers
Synergists
(Like the supporting characters of a story. S upporting, S ynergist
Connective tissue surrounding tendons where there is a long distance to attachment or the tendon pulls over a joint
Tendon sheath
Extensor of distal foreleg
Triceps brachii
Wasting away of muscle
Atrophy
