Enlarged ends of the long bone. Articulates with a second bone at a joint. covered by cartilage. Spongy bone covered by compact bone.

The ribs directly below the true ribs that attach indirectly to the sternum by cartilage or do not attach at all

Band of hyaline cartilage located near the proximal and distal ends of a growing long bone. also known as the growth plate. Longitudinal bone growth occurs

One of the contractile proteins in muscle; forms the thin filaments

Consists of a single motor neuron and the muscle fibers that are supplied by the motor neuron.

Myosin heads make contact with actin heads. Myosin heads rotate. Actin is pulled to the center of the sarcomere. Sarcomere shortens (muscle contracts).

Muscle attaches to the stationary bone

Found in walls of visceral muscle, tubes and passageways, bronchioles, and blood vessels. Involuntary muscle. Not striated. Stretchiness allows expansion of organs. Better capacity for regeneration

Largest muscle in the body. Forms the buttock and is the muscle on which you sit. Origins on the ilium, and sacrum and inserts on the femur. Rotates thigh laterally and extends the thigh at the hip

Muscles that oppose the action of another muscle

Flat muscle that covers the frontal bone. Extends from the cranial aponeurosis and insert in the skin above the eyebrows

Overused muscles that increase in size

Sternocleidomastoid, 3 Scalene muscles, and Trapezius

Group of four muscles: subscapularis, supraspinatus, infraspinatus, and teres minor. They attach (insertion) the humerus to the scapula (origin)

Dome-shaped muscle that separates the thoracic cavity from the abdominal cavity. Chief muscle of inhalation, or the breathing-in phase of respiration

Long extension that transmits signals away from the cell body. Contains the myelin sheath, the neurilemma, and the node of Ranvier

Helps to interpret sensory information. Ex: visual, auditory, somatosensory

Neuron impulse. A series of events cause the electrical charge inside the cell to move from its negative resting stat (-) to its positive depolarize state (+) and back to its negative resting state

Connects the spinal cord with higher brain structures. Composed of the midbrain, pons, and medulla oblongata

Contains the nucleus and is essential for the life of the cell. Receives signals from the dendrites and chooses which ones to send to the axon

Concerned with coordination of voluntary muscle activity. Major reflex center. Evaluates sensory input

Integrating system for the autonomic nervous system; regulation of temperature, water balance, sex, thirst, appetite, and some emotions.

Located in the back of the head, contains the visual cortex

Is the most important in the transmission of electrical signals. Enables their nervous system to act as a vast communication. 3 parts: denrites, cell body, and axon

Divided into 2 structures: the central nervous system (CNS) and the peripheral nervous system (PNS). Performs 3 general functions: a sensory function, an integrative function, and a motor function
