Study Notes
Anatomical Terms
- The term "brachium" refers to the arm.
- A sagittal plane divides the body into right and left sections.
- The abdomen is ventral to the gluteal region and caudal to the cervical region.
Synovial Joints
- Synovial joints contain a space and are lined with articular cartilage.
- They can be freely movable and categorized as tri-, bi-, or uni-axial.
- A false statement about them is that they are stronger than immovable joints.
Joint Movements
- Elbow joint movement around a horizontal axis is known as pronation.
- Hip joint movement around a vertical axis results in lateral rotation.
- Supination refers to the rotation of the forearm where the palm faces up.
Knee Joint Structure
- Menisci are the primary structures providing shock absorption at the knee joint.
- A stronger joint is more stable and less mobile.
Connective Tissue
- The extracellular matrix is the primary component of connective tissue.
- Functions of connective tissue include support, transport, framework, and storage; communication is not a function.
Cartilage
- Tendons are made of dense regular connective tissue.
- Chondroclasts are the cells that dissolve cartilage matrix.
- Cartilage is solid, avascular, and surrounded by perichondrium; however, it can grow by more than just peripheral addition.
- Fibrocartilage is best for shock absorption.
Bone Structure
- Osteoblasts are responsible for producing new bone.
- An osteon is the basic unit of compact bone, containing blood vessels, concentric lamellae, and osteocytes.
- Endochondral ossification begins with a cartilage model.
Muscle Tissue
- Smooth muscle is nonstriated, involuntary, and has a single nucleus.
- Myofilaments distribute the nerve's action potential deep into muscle fibers.
- Calcium is stored in the sarcoplasmic reticulum of muscle cells.
- The entire muscle is surrounded by epimysium.
Muscle Anatomy
- The "A band" contains the thick protein filaments responsible for striations.
- The orbicularis oculi muscle functions to close the eye.
- Temporalis is a muscle involved in mastication (chewing).
- The most superficial abdominal muscle is the external oblique.
- The rectus abdominis has vertical fiber orientation and it runs vertically.
- Muscles of the vertebral column primarily extend the spine.
Posterior Trunk Muscles
- The trapezius can depress, elevate, or retract the scapula but does not protract it.
- The triceps brachii muscle extends the arm and forearm at the shoulder and elbow.
Muscle Actions
- Anterior muscles inserting on carpal bones flex the wrist.
- The hamstring group extends the hip and flexes the knee joints.
- Muscles on the plantar foot flex the toes.
