The Spinal Column also known as ?
Vertebral Column
Spinal column made up of ?
Made up of individual irregular bones - vertebrae
what is the sections of the spinal column ?
Cervical vertebrae (7),thoracic vertebrae (12),Lumbar vertebrae (5),Sacral vertebrae (1), Coccygeal vertebrae (1)
Vertebrae explained, choose the right answers
Vertebrae are separated by intervertebral discs (fibrocartilage) - shock absorbers.
The Spinal Column in The arch houses the spinal cord.
True
Vertebra characteristics are , The processes are sites for muscle ___________ and provide_______ for movement.
attachment, leverage
The single,_______ projecting _________ process and the two _______projecting transverse processes vary in size among vertebrae.
dorsally , spinous, laterally,
The Spinal Column - Cervical Vertebrae
7 in dogs and cats, Atlas has “Wings of the Atlas”
Thoracic Vertebrae
Animals usually have the same number as pairs of ribs, Have very tall, spinous processes, Their lateral facets form joints with the ribs
Lumbar Vertebra
Dorsal to abdominal region, Have large, bulky bodies to support the abdominal contents (compared with the thoracic vertebrae which have the support of the ribs)
Sacral Vertebrae, Forms a_____ with the pelvis on each side called the ___________ . Sacral vertebrae are unique in that they fuse to form a single solid structure called the __________.
joint, sacroiliac joint , sacrum
Appendicular Skeleton
The forelimb = thoracic limb The hindlimb is = pelvic limb Ulna = Forms the Antebrachium (forearm) with the radius Humerus = The long bone of the upper arm (brachium)
These bones are numbered instead of named, starting at the medial side and working laterally.
Carpus
Each digit is made up of 2-3 bones called *(singular = phalynx).___________the individual bones that make up the digits.
Phalanges
Cats and dogs have another type of bone within their paws besides phalanges, carpals, metacarpals
phalanges, carpals, sesamoid, metacarpals
The calcaneal tuberosity of the fibular tarsal bone projects upward and backward to form the point of the hock
True
The ______________ of the fibular tarsal bone projects upward and backward to form the point of the hock
calcaneal tuberosity
Fibula
It does not support any significant weight but mainly serves as a muscle attachment site.
FActs about patella
largest sesamoid bone in the body, It helps protect the tendon as it passes down over the trochlea of the femur to insert on the tibial crest.
Match correct bones with their explanation
Obturator foramina: = Large holes on either side of the pelvic symphysis. Acetabulum: = The three bones of the pelvis come together here to form the concave ball-and-socket hip joint that tightly encloses the head of the femur. Pelvic/Pubic Symphysis: = Cartilaginous joint that ossifies with age and joins the two sides of the pelvis together ventrally. Pelvis - Pubis = Located medially and forms the cranial portion of the pelvic floor, while the ischium forms the caudal part.
Study Notes
Axial Skeleton
- Consists of the external bones of the cranium
- The spinal cord exits the skull through the foramen magnum
- The joint that connects the head with the neck is the atlanto-occipital joint
Middle Ear Bones
- The three tiny but important pairs of bones are known collectively as the ossicles
- Ossicles are hidden inside the middle ear
- The ossicles consist of the malleus, incus, and stapes
Skull
- The bony labyrinth is a thin layer of bone at the base of the middle ear
- It houses the middle and inner ear
- The anatomy of the bony labyrinth is different between humans and other animals
- The bony labyrinth surrounds the tympanic cavity and can become infected
Hyoid Bone
- The hyoid bone supports the tongue, larynx, and trachea
- It helps the animal swallow
- The hyoid bone is usually referred to as a single bone, but it is composed of several individual portions united by cartilage
Spinal Column
- Also known as the vertebral column
- Made up of 33 vertebrae
- The sections of the spinal column are:
- Cervical vertebrae (7)
- Thoracic vertebrae (12)
- Lumbar vertebrae (5)
- Sacral vertebrae (5)
- Coccygeal vertebrae (4)
- The arch of the vertebrae houses the spinal cord
- Vertebrae characteristics are:
- Processes are sites for muscle attachment and provide leverage for movement
- The single, spinous projecting dorsal process and the two transverse processes vary in size among vertebrae
Sacral Vertebrae
- Forms a pelvis on each side called the sacroiliac joint
