Limited Chest Expansion
Other organ systems affected like heart, great vessels, pulmonary, GI and GU systems
Subtalar joint
-btwn talus & calcaneus
frontal plane
Muscle develops tension as it shortens
(contracts-contracted muscle, concentric m
ie.   rectus femoris is concentric during knee extension
-A combination of ankle dorsi?exion, subtalar eversion, and forefoot abduction (toe-out)-Internally rotating radius where it lies diagonally across ulna, resulting in palm-down position of forearm
interosseous membrane
this holds the radioulnar articulations together

I: lateral surface of proximal shaft of radius
A: supinates the forearm
ditchlike groove containing a tendon or blood vessel
what do lymphocytes do?

In the evalution process, what part will tell you the most information
Functions of the Shoulder
Hand placement
Stabalization for hand use
Shock absorber for arm
a partial or complete tearing of fibers of a ligament
ruptured disk
compression of the spinal column causes two vertebrae to push together, crushing the hard ourter portion of the cartilage, tearing it. this can cause the soft inner portion of the disk to herniate, pushing out of the ruptured area. This can cause pinching of a spinal nerve.
Atrial natriuretic peptide (ANP)
released when atrial stretch-receptors sense too much blood volume. Causes kidney to excrete more Na+, and therefore more H2O, bringing blood volume back down to normal.
O: upper border manubrium of sternum, medial 1/3 clavical
I: mastoid process
A: flex, laterally flex, contralaterally rotate
Cervical Lateral Flexion

- Ear to shoulder

thick, clear fluid that lubricates the articular cartilage
sarcoplasmic reticulum
a complex system of membrane bound storage saces (modified endoplasmic reticulum) which collects and stores calcium.
renal cortex

McKenzie exercises
Good for disc but not stenotic conditions
Length tension
When the muscle is contracted and elongated real long, it takes alot of resistance and force to make a muscle stretch any further
largest of the movable vertebrae
- support the weight of the body
- interlocking articulation with other vertebrae
lumbar vertebrae
Cerebral cortex info
Area of highest level of control
Involved in choosing a course of action
Contains Primary Motor Cortex to send commands
Contains Somatosensory cortex
Weight Support
Line of gravity – anterior to normal dosiflexion of ankle
Thus, normal standing requires contraction of the plantar flexors (soleus)
Talus – "keystone"
All weight transmitted to foot through talus
Located somewhat medial (highest side)
What is synovial fluid?
-egg white like
-keeps joint apart
-dries up when you go to bed
-has pressure gradient
-keeps joints cool
-provides nutrition to articular cartilage
Mechanival Advantage
Ratio of the internal moment arm to the external moment arm
Bone MarkingsTypes of Cavities
Facets, Foramen, Fossa, Fovea, Meatus, Sinus, Sulcus
infraspinatus muscle

O: proximal anterior shaft of fibula and IM
I: dorsal base middle, distal phalanxes digits 2-5
A: extends digits 2-5, everts, dorsiflexes ankle
Characteristics of disc heights
During bedrest disc pressure is low.
Low pressure and hydrophilic nature of the dis cause cause dis to swell- disc herniation patients have more pain in the morning.
Weight bearing activities force water out of the disc- 1.1% variation in height during a single day.
Water content:
At birth - 88%
65-72% by age 75
less able to handle loads
May lead to microfracture and bony resorption of the vertebral endplates - eventual widow's and dowager's hump.
Lost of height with age with not a function of disc height - it is a function of bone loss.
Extensors of the Elbow joint
Triceps brachii: all heads, anconues
forces acting in and on the body that produce stability or mobility

-consideration of internal forces (body mass and muscular forces) and external forces (gravity)
Plane Joint
Two surfaces flat and allow gliding movement
Primarily uniaxial, however can move in more than one plane or axis
Ex. Carpal bones of wrist
What type of joint is the acromioclavicular?
irrregular plane

O axes
Q Angle
Angle formed by the line of pull of the quad muscles on the patella and the line of the patellar tendon.
Goniometer is used to
Goniometer is used to measure amount of movement in a joint or measure joint angles
humeral neck fracture
caused by a fall on the outstreched hand; common in the elderly is usually an impacted fracture

Name the 4 types of parallel muscles, and the 3 types of oblique muscles.  Give examples
1. Strap (Sternocleidomastoid)
2. Fusiform (Biceps
3. Rhomboidal (pronator quadratus)
4. Triangular (Pec Major)
1. Unipennate (looks like half a feather) (flexor pollicis longus muscle of hand)
2. Bipennate (feather) (rectus femoris of hip)
3. Multipennate (deltoid)
renin angiotensin systemREGULATES BLOOD PRESSURE.
1. Kidney senses low blood pressure or reduced Na+ filtration of glomerulus2. kidney secretes renin3. liver continuously secretes angiotensinogen to blood.4. renin contacts angiotensinogen in blood, it becomes angiotensin I5. Angiotensin I contacting ACE (present in most cells, but highest concentration in lungs) converts it to Angiotensin II6. Angiotensin II causes:- vasoconstriction of small vessels (rise in blood pressure)- Increased ADH secretion by posterior pituitary = increased thirst --> increased thirst = increased: drinking + fluids --> increased blood pressure- increased ALDOSTERONE secretion by Adrenal gland --> SALT reabsorption and potassium secretion increase by KIDNEY--> INCREASES BLOOD PRESSURE.
What are the characteristics of Type IIa muscle fibers?
*Moderate numbers of mitochondria
*Moderate resistance to fatigue
*Combination of aerobic and anaerobic
*Intermediate speed between Type IIb and Type I
*Very adaptable
Joints in the knee joint
tibiofemoral joint- medial and lateral compartment
Type II Collagen Fibers
Thinner and less stiff than Type I fibers; provide a flexible woven framework for maintaining the general shape and consistency of structures such as hyaline cartilage.
Bipennate muscles are described as
fibers run obliquely on both sides from a central tendon
Location of the top and bottom of the scapula marked by the thoracic vertebrae:
T3 and T7
hemoglobin - reduced in body called what?
anaemia. reduced oxygen carrying capacity.
Age related muscle changes
Slow phase - 10% loss from age 25-50
Rapid phase - 40% loss from age 50-80
Aging results in loss of fast fibers
Primary loss of muscle mass is due to inactivity.
Pennate muscle fibers
Stuff a lot of muscle fibers in small space, contract over short distance with great force
ACL injury in women
Women tend to land in more knee extension, internal rotation, and valgus position. This makes them more prone to ACL injury.
Women also are quads dominant in their legs.
Can train to prevent this by training the hamstrings, softening the landing, training the hip abductors, training the hip ER's.
Explain the properties outsides and underneath the bone.
-Most outer bone is cortical with cancellous underneath-Cortical bone – low porosity, 5 to 30% nonmineralized tissue-Cancellous – spongy, high porosity, 30 to 90%-Cortical is stiffer & can withstand greater stress, but less strain than cancellous-Cancellous is spongier & can undergo greater strain before fracturing

Back School

(Bar Graph Intervertebral Pressue without Chair)
Low - High

- Lying (low): 25 kg
- Lying on Side (middle): 75
- Standing up (middle): 100
- Standing flexed forward (High): 150
Movements of the Subtalar & Transverse Joint
combined 5 - 15 degrees
Why is the SC joint impt?
it's the only bony connection btwn the humerous and axial skelton.
The movement of the patella in patellofemoral joint
In full extension the patella rests above the interconylar groove.
At 20 degrees of flexion the inferior portion contacts the femur.
At 60-90 degrees of flexion there is the greatest contact.
At 135 degrees of flexion the superior portion is in contact with the femur.
What are the characteristics of the Axis?
Large tall body with dens (remnant of the body of the atlas) projecting upward to articulate with the atlas.
Dens means rigid vertical axis of rotations.
Bifid spinous peculiar to the axis - good reference point for palpation.

- Knee Extension (when hip is extended)
- Hip Flexion
