• Exam #1: Wednesday April 16th 1:30-2:50 in Hogness Auditorium• bring scantron• covers chapters 1, atlas A, 6-9• Material covered on Tuesday WILL be on exam #1
• Quiz #1 closes Monday at 11pm
• review session Tuesday at 7pm in T-435 Health Science Building
Name this cell.List one of it’s functions.
Name this space. What is in this space?
John broke his ulna, does heneed crutches?
The pelvis is made up of 3 bones thatfuse, name them.
Joints• Different type of joints
• fibrous• cartilaginous
• synovial• anatomy • stabilizers
• temporomandibular joint• anatomy• TMJ syndrome
• shoulder joint• anatomy• common injuries
• knee and ankle joint• anatomy• common injuriesStrider
Joint classification• manner or type of material by which bones articulate• relates to movement
Fibrous or cartilaginous synovial
Fibrous• bound by collagen fibers• little or no movement
Cartilaginous• linked by cartilage• some movement
CartilageCells: chondrocytes Chondro = cartilage
Fibers: collagen or elastin
Matrix: firm gel• chondroitin sulfates• proteoglycans
Perichondrium: dense, irregular CT with chondroblasts
• freely moveable
• articulating bones covered with articular (hyaline) cartilage
• bones separated by joint cavity
• joint cavity contains synovial fluid
• joint is enclosed by joint capsule
Synovial joints
Ligaments (extracapsular)
Joint cavity (contains synovial fluid)
Joint (articular) capsule(Synovial membrane + fibrous capsule)
Articular (hyaline) cartilage
Parts of a synovial joint
Synovial fluid and warming up
Bursa• sac filled with synovial fluid• between muscles or tendons and bones• for protection and sliding• bursitis - inflammation
Tendon Sheaths• elongated bursae• wrap around a tendon• for protection and sliding• tenosynovitis• tendonitis
1. Depress & elevate2. Medial & lateral excursion3. Protraction & retraction
Temporomandibular joint (TMJ)
Mandibularfossa
• Exam #1: Wednesday April 16th 1:30-2:50 in Hogness Auditorium• bring scantron• covers chapters 1, atlas A, 6-9• Material covered on Tuesday WILL be on exam #1
• Quiz #1 closes Monday at 11pm
• review session Tuesday at 7pm in T-435 Health Science Building
• Exam #1: Wednesday April 16th 1:30-2:50 in Hogness Auditorium• bring scantron• covers chapters 1, atlas A, 6-9• includes material covered today
Joints
Humeroscapular joint (Glenohumeral)
articulating bones?
• flex & extend• hyperextend• abduct & adduct• medial & lateral rotation• circumduction
What about protraction &retraction of the scapula?
Sternoclavicular joint
Scapular anatomy• acromion• spine • coracoid process• glenoid cavity• AC joint

3. What is this? Function?
1. What is this? Function?
2. What is this? Function?
4. When the head of the humerus comes out of the glenoid fossa, what is that injury called?
Tibiofemoral joint (knee)• articulating bones
• tibia – femur(patellofemoral joint)
• movements- modified hinge• flex• extend• rotation when flexed• “locking” when fully extended
Lateral meniscusMedial meniscus
Menisci = Fibrocartilage pads
Knee flexed
Patellar surfaceMedial & lateral condyles
Tibial plateau(proximal end of tibia)
Anterior Posterior
meniscus
Medial (tibial)collateral ligament
Intracapsular & extracapsular ligaments of knee
Ant. Cruciate lig.
Post. Cruciate lig.
Lateral (fibular)collateral lig.
PCL: anterior displacement of femur when knee if flexed hyperflexion
ACL: posterior displacement of femur when knee is extended hyperextension
1. Name this structure
2. Name this structure (be specific)
3. Give one function of the structure in #2 (be specific)
4. List at least 6 movements that theshoulder can make
5. List at least 4 movements that theTMJ can make
retinaculum
Medial (deltoid) ligaments
Calcaneal (Achilles) tendon
Lateral collateral ligaments(Anterior talofibular ligament –Sprained during inversion)
1. Something important you learned today.
2. Any important questions that remain unanswered.
