Osseous Tissue
This microscopic structure consists of concentric lamellae surrounding a central canal containing blood vessels and nerves.
Osteons (Haversian System)
This vertebra allows rotation of the head and contains the dens.
Axis (C2)
This bone of the pectoral girdle articulates with the sternum at the sternoclavicular joint.
Clavicle
This type of synovial joint allows movement in one plane, such as the elbow.
Hinge Joint
This bone marking is a large roughened projection often used for muscle attachment
Tuberosity
These microscopic channels connect lacunae and allow osteocytes to exchange nutrients and wastes.
Canaliculi
These openings in cervical vertebrae allow passage of vertebral arteries.
transverse foramina
This projection of the scapula forms the highest point of the shoulder and articulates with the clavicle.
This joint between the atlas and axis allows rotational movement of the head.
Pivot Joint
This smooth, flat articular surface forms joints between bones such as those found in the carpals.
Facet
Bone growth in length occurs at this structure, where cartilage is gradually replaced with bone tissue.
This skull bone contains the sella turcica that houses the pituitary gland.
Sphenoid Bone
This notch on the ulna articulates with the trochlea of the humerus to form the elbow hinge joint.
trochlear notch
This structure within synovial joints reduces friction between bones during movement.
Synovial Fluid
This narrow slit-like opening allows passage of nerves or blood vessels.
Fissure
This process replaces hyaline cartilage with bone during fetal development and growth of long bones.
Endochondral Ossification
This cranial bone forms the majority of the hard palate and contains the palatine process.
Maxilla
This depression on the humerus receives the head of the radius during elbow flexion.
Radial Fossa
This type of joint allows movement in two planes and is found at the wrist (radiocarpal joint).
Condyloid Joint
This rounded articular projection forms part of a joint, such as those on the femur.
Condyle
This hormone increases blood calcium levels by stimulating osteoclast activity.
parathyroid hormone (PTH)
This structure of the vertebral column is formed by the articulation of vertebral arches and protects the spinal cord.
vertebral canal (vertebral foramen)
This region of the femur connects the head of the femur to the shaft and is a common site of fractures in elderly patients.
Femoral Neck
This fibrocartilaginous structure found in some synovial joints improves joint stability and distributes weight.
Meniscus (Articular Disc)
This very large rounded projection on the femur serves as an attachment site for powerful hip muscles.
Trochanter
