Lab Book Flashcards
The junction of a skeletal muscle to bone.
Attachment
What are the three types of attachments?
Tendon, Aponeurosis, Fleshy
An extension of the epimysium that consists of dense connective tissue.
Tendon
Dense fibrous connective tissue much like the tendon but organized into a thin sheet of tissue.
Aponeurosis
An apparent direct attachment of muscle to the bone.
Fleshy
The attachment at the more moveable end of the muscle.
Insertion
The body movement that a contraction pf the muscle will produce.
Action
The muscle that twitches the skin to remove flies.
Cutaneous Trunci
Covered cranially by the superficial pectoral.
Deep Pectoral
Y shaped muscle with three parts
Brachiocephalicus
partially covered by brachiocephalicus
omotransversarius
Thin triangle muscles lies over the dorsal part of the scapula
Trapezius
Triangle shaped muscle lies caudal to the scapula and covers much of the thoracic wall
Latissimus Dorsi
The name comes from the serrated appearance of the muscle on the ventral aspect of the thoracic portion, divided into two parts.
Serratus ventralis
What are the two parts of the serratus ventralis?
cervical and thoracic
Forms the jugular groove, attaches the sternum to the head, divided into two parts
Sternocephalicus
What are the two parts of the sternocephalicus?
mastoid and occipital
largest muscle on the head and is found on the lateral and dorsal aspects of the skull, between the ears
temporalis
large muscle found ventral to the zygomatic arch, lies on the lateral surface of the ramus of the mandible, cheek region, covered by the aponeurosis
masseter
divided into two parts that fuse before they insert
deltoideus
What are the two parts of the deltoideus
scapular and acromion
Fills the ______ fossa caudal to the spine of the scapula
Infraspinatus
Fills the ______ fossa cranial to the spine of the scapula
Supraspinatus
occupies the ______ fossa on the medial aspect of the scapula
subscapularis
lies caudal to the subscapularis, tendon of insertion joins that of the latissimus dorsi
teres major
crainomedial aspect of the humerus, only one head in animals
biceps brachii
lateral side of the humerus
brachialis
caudal aspect of the humerus, three heads in most animals BUT carnivores have a fourth head called the accessory head
triceps brachii
What are the three heads of the triceps brachii
long, medial, lateral
most cranially located muscle in the forearm, always present in cats and usually present in dogs, runs beside the cephalic vein
brachioradialis
cranial aspect of the radius and deep to the brachioradialis
extensor carpi radialis
lies caudal to the extensor carpi radialis on the lateral side of the foreleg
common digital extensor muscle
smaller than the common digital extensor and lies just caudolateral to it
lateral digital extensor
lies caudomedial to the ulna and covers the deep digital flexor
superficial digital flexor
Has three heads of origin, tendons of all three heads fuse at the carpus to form a single tendon and then subdivide to attach to the palmar aspect of each digit
deep digital flexor
Four small muscles lie deep to the deep digital flexor on the palmer aspect of the four metacarpal bones, act as flexors of the metacarpophalangeal joint
manus (muscles of the forefoot)
small triangular muscle overlies the caudal part of the middle gluteal
superficial gluteal
large egg shaped muscle lies cranial to the superficial gluteal and caudal to the tensor fascia latae
middle gluteal
fan shaped muscle that is totally covered by the middle gluteal
deep gluteal
longest and widest muscle of the thigh and covers the entire caudolateral aspect, spans three joints and can affect all three, tendon of muscle contributes to the formation of the achilles tendon
biceps femoris
straplike muscle lies medial to the biceps femoris and lateral to the semimembranosus, tendon of this muscle also contributes to the common achilles tendon
semitendinosus
wedged between the biceps femoris laterally and the gracilis and adductor muscles medially
semimembranosus
made up of two straplike parts that lie on the cranial and craniomedial surfaces of the thigh
sartorius
large, wide, flat muscle covers the caudomedial surface of the medial thigh
gracilis
What borders make up the femoral triangle?
sartorius, pectineus and adductor muscles and body wall
small spindle shaped muscle that makes up the femoral triangle
pectineus
consists of four heads that fuse distally to form a common tendon, most powerful extensor of the stifle
quadriceps femoris
What are the four heads of the quadriceps femoris?
rectus femoris, vastus lateralis, vastus medialis, vastus intermedius
This muscle is held in position near the tarsal joint by the extensor retinaculum
cranial tibial
spindle shaped muscles lies lateral to the cranial tibial muscle and partly covered by it, tendons of this muscle run under the proximal extensor retinaculum
long digital extensor
often called the calf muscle, forms the bulk of the achilles tendon
gastrocnemius
spindle shaped muscle arises from the lateral supraconylar tuberosity of the femur, tendon of insertion twists medially around that of the gastrocnemius to insert of the sides of the tuber calcanei and phalanges
superficial digital flexor
lies deep to the superficial digital flexor, tendons from both heads join near the tarsus and the divide to send a small tendon to insert on each of the four digits
deep digital flexor
heavy band of connective tissue that inserts on the tubber calcanei
common calcanean tendon, aka achilles tendon
What five muscles make up the common calcanean tendon?
gastrocnemius, superficial digital flexor, semitendinosus, gracilis, biceps femoris
