    Study Notes

    Skeletal System

    • The axial skeleton includes the bones of the skull, neck, and trunk.
    • There are 2 long bones in the forearm.
    • The pectoral and pelvic girdles contain the scapula, clavicle, pelvis, and sacrum bones.

    Bones and Features

    • A tuberosity is a bony feature.
    • A foramen is a hole in a bone that allows blood vessels or nerves to pass through.
    • A bony feature refers to a projection or marking on a bone.

    Joints

    • There are 3 types of joints: synovial, cartilaginous, and fibrous.
    • Synovial joints are characterized by the presence of synovial fluid and are capable of movement.
    • All joints contain ligaments, which connect bones to each other.

    Muscles and Tendons

    • The function of skeletal muscle is to move the body's skeleton.
    • Tendons connect muscles to bones and facilitate movement.
    • An aponeurosis is a type of tendon that is flat and sheet-like.
    • The attachments of the biceps brachii muscle are the scapula, radius, and ulna.
    • The innervation of the deltoid muscle is the axillary nerve.
    • The actions of the deltoid muscle include abduction, flexion, and extension of the shoulder joint.

    Muscle Physiology

    • During contraction, the origin and insertion of a muscle swap places.
    • A stretch reflex is a rapid, involuntary contraction of a muscle in response to stretching.
    • Without a functioning motor nerve supply, a muscle will atrophy.
    • Muscle strain refers to a stretched or torn muscle, while paralysis is the loss of motor function.
    • Spasticity refers to increased muscle tone, while atrophy is a decrease in muscle size.
    • Hypertrophy is an increase in muscle size.

    Reflexes

    • Reflexes test the ability to move and power of movement by testing muscle and nerve function.
    • The two main types of skeletal muscle reflexes are stretch reflexes and Golgi tendon reflexes.
