Module 1: Anatomy of the SacroPelvic Region.pdf Flashcards
(36 cards)
Name the Bones of the Pelvis
Made of the union of three bones
* Ilium, ischium, pubis
2 major muscles attaching to the ilium
- Gluteus medius
- Gluteus profundus
The Tuber sacrale has 2 different names, what are they
PSIS (posterior superior iliac spine)
Dorsal iliac spine
First palpable sacral tubercle in a horse versus a dog
Horse - S2
Dog- S1
What is the segmental contact point for PI ilium
Tuber sacrale – PSIS, dorsal iliac spine
Name the structure that is directly anterior to the tuber sacrale (PSIS, dorsal iliac spine)
Name the 3 reference names
Tuber coxae
Ventral iliac spine
ASIS (anterior superior iliac spine)
What is the tuber coxae a segmental contact point for
AS ilium
What is the segmental contact point for AS ilium
Tuber coxae
ASIS
ventral iliac spine
The tuber coxae is the major muscle attachment for
superficial gluteal m.,
EAO and IAO and
tensor fascia latae m
points you touch on the animal to make the adjustment are known as?
Segmental contact points
What part of the ischium to the hamstring muscles attach to?
Ischial tuberosity
What is the ischial tuberosity a segmental contact point for adjusting?
AS ilium
What part of the pelvis provides attachment for rectus abdominus
Pubis
Part of the pelvis thats formed by all 3 bones, creates the socket portion of ball and socket joint for hip?
________________
Acetabulum
Opening in the pelvis formed by ischium and pubis
Obturator foramen
When do all 3 bones of the pelvis unite in the dog versus the horse (include when secondary centers ossify)?
Dog: all 3 bones by 6 months (secondary centers 2 years-why OFA rads(xrays) can’t be taken until 2 years of age
Horse: all 3 bones unite by 1 year, secondary ossification centers of pelvis 5 years
The sacral segments vary in different animals. state how many segents in each set of animals and when they fuse by
dog/cat
cow/horse
goats/sheep/pig
- Dog & cat – fusion of 3 segments
- Fuse by age 6 months
- Ox and horse – 5 segments
- Fuse by age 4
- Goats, sheep, hog – 4 segments
What is the first palpable sacral tubercle on horse versus dog?
horse: s2
dog: s1
Where is the sacral base on the dog versus the horse
both are between the tuber sacrale (slightly in the middle and back)
you will feel on the dog S1
on the horse your sacral base is S2 (the first palpable)
Segmental contact point for lateral aspect of sacrum
Sacral Apex (there can be right or left)
Pronounced slope to croup predisposes to _______
strain and extra stress on hip joint (German
Shepherds)
lumbar
Upright posture predisposes to problems in the ______
stifle
(due to hyperextended hocks and upright posture)
What * Provides point for muscle attachment
* Biceps femoris, gluteus medius and superficialis, semimembranosus,
longissimus mm.
Sacrotuberous ligament
What species lacks a sacrotuberous ligament
Cats (Feline)
