| Question | Answer |
|---|---|
| The individual muscle fibers are covered by a connective tissue membrane called the | endomysium |
| Muscles that move the forearm include... | 1) brachioradialis 2) pronator terses 3) biceps brachii |
| A muscle with fascicles that insert into only one side of the tendon is categorized as | unipennate |
| The fibrous connective tissue that surrounds the entire muscle and is outside the epimysium and tendon is called the | fascia |
| In addition to the Pectoral's major, another muscle that displays this pattern of fascicle arrangement is Latissimus dorsi | convergent |
| An example of a muscle with this type of fascicle arrangement is the orbicularis oris. | circular |
| The biceps brachia has this fascicle arrangement, which maximizes the range of motion possible. | Parallel |
| The continuous low level of sustained contraction maintained by all skeletal muscles is muscle | tone |
| This arrangement of muscle fascicles tends to be triangular in shape. The Pectoral's major is an example of a muscle with this type of muscle fascicle arrangement. | convergent |
| Muscles that move the wrist, hand, and fingers can be | extrinsic or intrinsic |
| The long axes of the fascicles run parallel to the long axis of the muscle is a description of this type of fascicle arrangement. | parallel |
| The common tendon of the gastrocnemius and coleus is called the | calcaneal tendon |
| The Sartorius muscle, a thin straplike muscle would have muscle fascicles arranged in | parallel |
| The point of attachment that does not move when the muscle contracts is the | origin |
| The term________ is used to describe a muscle that directly performs a specific movement. | agonist |
| Muscles with this type of muscle fascicle arrangement are either fusiform or straplike in appearance. | parallel |
| The muscle fascicle arrangement for Orbicularis oris is best characterized as | circular |
| A muscle with fascicles that insert into the tendon from both sidesis categorized as | bipennate |
| The lymphatic system, like the circulatory system, is a closed circuit. | True |
| Small distinct regions of gray matter in the CNS are called: | nuclei |
| Nerves that contain mostly afferent fibers are called ________ nerves. | sensory |
| The nervous system can be divided: | 1) according to its structure 2) according to direction of information flow 3) by control of effectors |
| The largest and most numerous types of neuroglia are the: | astrocytes |
| Which of the following compounds cannot cross the blood-brain barrier? | Dopamine |
| Which part of the vertebral column has one more pair of nerves coming from it than it has vertebrae? | Cervical |
| Visceral effectors are innervated by sympathetic fibers. | True |
| The phrenic nerve is found in the _______ plexus. | cervical |
| Facts about the spinal cord | 1) The spinal cord does not completely fill the spinal cavity 2) The spinal cord extends from the foramen magnum to the first lumbar vertebra 3) The spinal cord has anterior and posterior grooves that almost divide the cord into symmetrical halves |
| Small branches from the cervical plexus join which two cranial nerves? | Hypoglossal and accessory |
| parasympathetic neuron cell bodies are located in | nuclei of the brainstem and the lateral gray columns of the sacral cord. |
| A type of blood cell produced by lymph nodes is called a (n) | monocyte |
| The lymph nodes located just above the bend of the elbow are called the ______ lymph nodes. | supratrochlear |
| During their residence in the thymus, pre-T cells develop into _____, cells that proliferate as rapidly as any in the body. | thymocytes |
| Which of these structures is not found in the left lung? | Horizontal fissure |
| The approximate length of the trachea, or windpipe, is ____ cm. | 11 |
| The more common name for the pharynx is the: | throat |
| The cribriform plate: | separates the nasal and cranial cavities |
