Skeletal Flashcards
Pivot joint
uniaxial joints and is the vertebrae in the neck area
Hinge joint
uniaxial joints and is in the elbow
Saddle joint
biaxial joints and is in the thumb
Condyloid Joint
biaxial joints and
How many bones are in the cranium?
22 bones 21 of which cant move
What is the only movable bone in your skull?
mandible (lower jaw), which is the only moveable bone of the skull.
What are the five vertebral regions (from superior to inferior)?
Cervical vertebrae,Thoracic vertebrae,Lumbar vertebrae
How many vertebrae are in cervical?
7
How many vertebrae are in thoracic?
12
How many vertebrae are in lumbar?
5
Scoliosis
an abnormal, lateral curvature, accompanied by twisting of the vertebral column
Kyphosis
also referred to as humpback or hunchback, is an excessive posterior curvature of the thoracic region.
Lordosis
or swayback, is an excessive anterior curvature of the lumbar region and is most commonly associated with obesity or late pregnancy
Pivot joint
a rounded portion of a bone is enclosed within a ring formed partially by the articulation with another bone and partially by a ligament.
Hinge Joint
the convex end of one bone articulates with the concave end of the adjoining bone
Saddle Joint
both of the articulating surfaces for the bones have a saddle shape, which is concave in one direction and convex in the other
Plane Joint
the articulating surfaces of the bones are flat or slightly curved and of approximately the same size, which allows the bones to slide against each other
Condyloid Joint
the shallow depression at the end of one bone articulates with a rounded structure from an adjacent bone or bones.
Ball and Socket Joints
the rounded head of one bone (the ball) fits into the concave articulation (the socket) of the adjacent bone.
Flexion/Extension
Movements that take place within the sagittal plane and involve anterior or posterior movements of the body or limbs.lexion (anterior flexion) is an anterior (forward) bending of the neck or body, while extension involves a posterior-directed motion.Lateral flexion is the bending of the neck or body toward the right or left side
Adduction/Abduction/Circumduction
Abduction-Moves the limb laterally away from the midline of the body
Adduction-Brings the limb toward the body or across the midline
Circumduction-Movement of a body region in a circular manner, in which one end of the body region being moved stays relatively stationary while the other end describes a circle.
Rotation
can occur within the vertebral column, at a pivot joint, or at a ball-and-socket joint.
Supination/Pronation
Pronation is the motion that moves the forearm from the supinated (anatomical) position to the pronated (palm backward) position.Supination is the opposite motion, in which rotation of the radius returns the bones to their parallel positions and moves the palm to the anterior facing (supinated) position.
Dorsiflexion/Plantar Flexion
Lifting the front of the foot, so that the top of the foot moves toward the anterior leg is dorsiflexion.while lifting the heel of the foot from the ground or pointing the toes downward is plantar flexion.
