What are the Muscles of the Eyebrow and Nose?

* Corrugator
* Orbicularis Oculi
* Procerus
* Nasalis

92

Name the Brow Muscle:

* The muscle located beneath the frontalis and orbicularis. It draws the eyebrow down and wrinkles the forehead vertically.

Corrugator

93

Name the Brow Muscle:

* The ring muscle of the eye-socket; it closes the eye.

Orbicularis Oculi

94

Name the Nose Muscle:

* Lowers the eyebrows and causes wrinkles across the bridge of the nose.

Procerus

95

Name the Nose Muscle:

* A two part muscle which covers the nose. Includes the transverse part and the alar part, which flair the nostrils.

Nasalis

96

What are the Muscles of the Mouth?

* Buccinator
* Depressor anguli oris
* Depressor labii inferioris
* Levator anguli oris
* Levator labii superioris
* Mentalis
* Orbicularis oris
* Risorius
* Zygomaticus major and minor

97

Name the Muscle of the Mouth:

* The thin, flat muscle of the cheek between the upper and lower jaw that compresses the cheeks and expels air between the lips, as in when blowing a whistle.

Buccinator

98

Name the Muscle of the Mouth:

* a.k.a. Triangularis. The muscle extending along side the chin that pulls down the corners of the mouth.

Depressor Anguli Oris

99

Name the Muscle of the Mouth:

* The muscle surrounding the lower lip that depresses it and draws the lower lip to one side.

Depressor Labii Inferioris

100

Name the Muscle of the Mouth:

* a.k.a. Caninus. A muscle that raises the angle of the mouth and draws it inward.

Levator Anguli Oris

101

Name the Muscle of the Mouth:

* A muscle that elevates the lip and dilates the nostrils, as in expressing distaste.

Levator Labii Superioris

102

Name the Muscle of the Mouth:

* The muscle that elevates the lower lip and raises and wrinkles the skin of the chin.

Mentalis

103

Name the Muscle of the Mouth:

* The flat band around the upper and lower lips that compresses, contracts, puckers, and wrinkle the lips.

Orbicularis Oris

104

Name the Muscle of the Mouth:

* The muscle that draws the corner of the mouth out and back, as in grinning.

Risorius

105

Name the Muscle of the Mouth:

* Muscles extending from the zygomatic bone to the angle of the mouth that elevate the lip, as in laughing.

Zygomaticus Major and Minor

106

What are the Muscles that Attach the Arms to the Body?
Describe them.

* Latissimus dorsi: a large, flat, triangular muscle that covers the lower back.

* Pectoralis major and minor: muscles of the chest that assist the swinging movements of the arm.

* Serratus anterior: a muscle of the chest that assists in breathing and in raising the arm.

107

What are the Muscles of the Shoulder and Arms?

* Trapezius
* Biceps
* Deltoid
* Triceps
* Extensors
* Flexors
* Pronators
* Supinator

108

Name the Shoulder Muscle:

* Covers the back of the neck, shoulders, and upper and middle region of the back; shrugs shoulders and stabilizes the scapula.

Trapezius

109

Name the Shoulder Muscle:

* Produce the contour of the front and inner side of the upper arm; they lift the forearm, flex the elbow, and turn the palms outward.

Biceps

110

Name the Shoulder Muscle:

* A large, triangular muscle covering the shoulder joint that allows the arm to extend outward and to the side of the body.

Deltoid

111

Name the Arm Muscle:

* A large muscle that covers the entire back of the upper arm and extends the forearm.

112

Name the Arm Muscle:

* Muscles that straighten the wrist, hand, and fingers to form a straight line.

Extensors

113

Name the Arm Muscle:

* Extensor muscles of the wrist, are involved in flexing the wrist.

Flexors

114

Name the Arm Muscle:

* Muscles that turn the hand inward so that the palm faces downward.

Pronators

115

Name the Arm Muscle:

* Muscle that rotates the radius outward and the palm upward.

Supinator

116

What are the muscles of the Hand?
Describe them.

* Abductors: muscles that draw a body part away from the midline of the body.

* Adductors: muscles that draw a body part inward toward the median axis of the body.

117

The scientific study of the structure, function, and pathology of the nervous system.

Neurology

118

What are the 3 main subdivisions of the Nervous System?

* Central Nervous System (CNS)
* Peripheral Nervous System (PNS)
* Autonomic Nervous System (ANS)

119

I consist of the brain, spinal cord, spinal nerves, and cranial nerves. I control consciousness and many mental activities, voluntary functions of the 5 senses, and voluntary muscle actions.

What nervous system am I?

Central Nervous System

120

I connect the peripheral parts of the body to the central nervous system. I have both sensory and motor nerves. My job is to carry messages to and from the central nervous system.

What nervous system am I?

Peripheral nervous system (PNS)
