What do we call joints that are connected by a sheet of fibrous tissue?
Fibrous Joint
What joint is in the scull and are tightly packed?
Sutures
When you have space between the bones and a sheet of fibrous tissue? (articulation)
Syndismosis (sheet of tissue not closely packed like tissues)
What are the features of a synovial joint?
Capsule, Cartilage, and Cavity
Which synovial joints are classified as biaxial?
Modified Hinge, Saddle
Describe a closed packed position? and what happens with the ligaments?
-e.g. Hip joint when you EXTEND, ABDUCT, and INTERNALLY ROTATE.
-Minimizes joint surface/brings everything together.
*MAXIMAL ARTICULAR SURFACE CONTACT
-LIGAMENTS ARE AT THEIR MAXIMUM LENGTH
*INCREASE IN STABILITY & DECREASE IN MOBILITY
Is GH joint supported by ligaments?
No, it is mainly supported by muscles
Closed paced position for GH Joint?
Maximum Abduction and External Rotation
*GH joint is rarely in a closed packed position
What do we call an area where a tendon inserts into a bone?
Tendoperiosteal Junction
What is a sheet like tendon?
Aponeurosis
What type of contraction happens when we are trying to control or slow a movement?
Eccentric
When there is no movement at the joint and there is an equal force in resistance?
Isometric
What do we call muscles that oppose the prime mover?
Antagonist
What do we call muscles that assist the prime mover?
Synergist
How many tarsal bones are in the foot?
7
How many metatarsals bones are in the foot?
5
How many phalanges bones are in the foot?
14
How many bones are in the foot?
26
Head of Talus articulates with the posterior aspect of which bone?
Navicular
What bone articulates with the bases of the 4th and 5th metatarsals?
Cuboid
There is a groove on the talus and a groove on the calcaneus and where they fit together creates a hollow on the lateral aspect of the foot. What is this called? *Is where anterior talofibular ligament can be isolated
Sinus Tarsi
Where on the foot will you find 2 sesamoid bones?
Head of the first metatarsal & plantar surface
What is a sesamoid bone?
Bone embedded in a tendon
Inversion & Eversion happen along which plane? and which joint?
Frontal/Coronal, Subtaylor joint
Dorsiflexion & Plantar Flexion happen at which joint?
Talocrual
Where else in the body will you see dorsiflexion and plantar flexion?
Nowhere
Adduction and Abduction of the forefoot happen along which plane?
Transverse
Supination is a combination movement comprised of which three movements? (Foot)
Plantar Flexion/Inversion/Adduction of the forefoot
Which direction would you have to move from Gerdy’s tubercle to locate the tibial tuberosity?
Inferomedial
With Dorsiflexion where does the head of the fibula move?
Posterior & Superior *Facet itself is on a oblique angle so as it moves up it moves back
What type of joint is the talocrural joint?
Hinge (uniaxial)
*Majority of toes are hinge joints
What type of joint is the subtaylor joint?
Plane (uniaxial)
*Majority of intertarsal joints are plane
Ball and socket joint in the foot is the __________________.
Talocalcaneonavicular
Majority of metasarsalphalangeal joints are?
Condoloyid
Which ligament in the ankle helps to restrict eversion?
Deltoid Ligament (Vertical Fibres)
*Vertical fibres would restrict straight up eversion, anterior fibres would restrict plantar flexion with eversion, & posterior fibres would restrict dorsiflexion with eversion
Which Ligament would restrict plantar flexion with eversion
Anterior Tibiotaylor & tibionavicular (anterior fibres)
*Vertical fibres would restrict straight up eversion, anterior fibres would restrict plantar flexion with eversion, & posterior fibres would restrict dorsiflexion with eversion
Which Ligament would restrict dorsiflexion with eversion?
Posterior tibiotaylor (posterior fibres)
*Vertical fibres would restrict straight up eversion, anterior fibres would restrict plantar flexion with eversion, & posterior fibres would restrict dorsiflexion with eversion
Which actions are restricted by the anterior taylorfibular ligament (ATFL)?
Inversion with plantarflexion
Which Ligament in the ankle restricts straight up inversion? *It runs between calcaneus and lateral malleolus?
Calcaneofibular Ligament
What 4 things maintain the arches of the foot?
- Shape of the interlocking bones/the way they fit together (primary)
- Ligaments
- Fascisa
- Muscles
What is the theory of the windlass mechanism of the foot?
-Fascia runs from the medial calcaneotubercle crossing over the metatarsalphalangeal joints into the toes therefore extension of the toes will tighten the plantar fascia and draw the calcaneus forward increasing the longitudinal arches of the foot
Which three directions does the head of the femur face?
- Anterior
- Superior
- Medial
What is the rough ridge with 2 lips running down the posterior surface of the femur?
Linea Aspera
