Equine Anatomy: The Nervous and Muscular Systems
Questions in this quiz (25)
1Central Nervous System
- A(CNS) Consists of the brain and spinal cord, which perform very specific functions
- BConsists of nerves
2Peripheral Nervous System
- APNS Consists of numerous pairs of nerves that exit the spinal column at vertebral level (spinal bones; Vertebrae)
- BPNS Consists of octic nerves that enhance peripheral vision
3What are Afferent Nerves, and what do they do?
- ASensory nerves that carry information FROM the body TO the central nervous system (CNS)
- BSensory nerves that carry information TO the body FROM the central nervous system (CNS)
4What are Efferent Nerves, and what do they do?
- AMOTOR NERVES which carry information FROM the CNS TO the body parts.
- BMotor NERVES which carry information TO the CNS from the body parts.
5What is ANS, and what does it do?
- AAUTONOMIC NERVOUS SYSTEM, maintains a stable internal environment. Governs the vital organs and their complex functions that are normally carried out INVOLUNTARILY. Ex. Breathing, circulation, digestion, elimination and the immune response. Has TWO major divisions: The Sympathetic and The Parasympathetic.
- BAUTOMATIC NERVOUS SYSTEM, maintains a stable internal environment. Governs the vital organs and their complex functions that are normally carried out VOLUNTARILY. Ex. Breathing, circulation, digestion, elimination and the immune response. Has THREE major divisions: The Sympathetic and The Parasympathetic and The Nervous
6The Sympathetic Nervous System governs the flight or fright reaction.
- ATrue
- BFalse
7The Sympathetic Nervous System decreases heart rate, blood pressure etc.
- ATrue
- BFalse
8What is the Parasympathetic Nervous System, and what does it do?
- ARegulates INVOLUNTARY activities that keep the body running smoothly under normal, everyday conditions.
- BRegulates VOLUNTARY activities that keep the body running smoothly under stressful situations.
9What is a muscle?
- AA muscle is the fleshy part of the body that enables the skeleton to move. Contracts in response to nervous command.
- BA muscle is the fleshy part of the body that enables the tendons to move. Contracts in response to nervous command.
10What are skeletal muscles?
- ASkeletal muscles involuntary; they do not function with the horses movement.
- BSkeletal muscles are voluntary; they function in the horses movement.
11These muscles are involuntary, or autonomic; they play a part in the digestive, respiratory, circulatory, and urogenital systems.
- ACardiac and Smooth Muscles
- BSkeletal and Cardiac Muscles
- CSmooth and Skeletal Muscles
- DCardiac and Skeletal Muscles
12The Muscle Belly is the fleshy part of the muscle that contracts in response to a nervous command.
- ATrue
- BFalse
13The Muscle Spindle and the Golgi Apparatus are the same thing.
- ATrue
- BFalse
14Nerve endings of the muscle spindle prevent overstretching of the muscle fibers.
- ATrue
- BFalse
15What are the two types of sensory nerve endings?
- AOrigin Tendon and Insertion Tendon
- BFast Twitch Fibers and Slow Twitch Fibers
- CGolgi Apparatus and Muscle Spindle
16What is the Golgi Apparatus?
- ASeals the capsular ligament (Joint Capsule) which produces a viscous, lubricating, secretion.
- BOne of two types of sensory nerve endings in the muscles. Nerve endings of this prevent over stretching of the muscle fibers. This nerve fiber coils around the length of the muscle bundle.
- COne of two types of sensory nerve endings in the muscles. These nerve endings send feedback impulses to the brain as to the whereabouts of the muscles, this process is referred to as proprioception (being aware of the body and its actions)
17What is a contracture?
- AConnective tissue that covers, supports and separates the muscle bundles and the whole muscle itself.
- BA dense white fibrous tissue, much like that of a ligament.
- CThe portion of the muscle that attaches to the bone.
- DWhen the muscles do not release, staying contracted, resulting in a spasm.
18Fast Twitch Fibers are....
- AAEROBIC FIBERS; they NEED oxygen in order to do their job. They also have strong endurance qualities. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.
- BANAEROBIC FIBERS; they DO NOT need oxygen to work and are therefore able to deliver the quick muscular effort required for a sudden burst of speed. They are only able to perform for a short amount of time. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.
19Slow Twitch Fibers....
- AAre ANAEROBIC FIBERS; they DO NOT need oxygen to work and therefore able to deliver the quick muscular effort required for a sudden burst of speed. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.
- BAre AEROBIC FIBERS; they need oxygen in order to do their job. They require a good supply of blood to bring oxygen to them and to remove waste products created during exercise. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.
20What is connective tissue?
- ACovers, supports, and separates the muscle bundles and the whole muscle itself.
- BA dense, white, fibrous tissue, much like that of a ligament.
21What is Fascia?
- AA dense white fibrous tissue, much like that of a ligament.
- BCovers, supports and separates the muscle bundles and the whole muscle itself. This arrangement allows for greater support, strength, and flexibility in the movement between each of the muscle groups.
- CMuscles are attached to the bone by Fascia.
22What attaches bone and muscles together?
- AFascia
- BTendons
- Cligaments
23What does the Insertion Tendon do?
- AAttaches the muscle to the least movable bone
- BAttaches the muscle to the movable bone, so that on contraction the insertion is brought closer to the origin.
24What is the Origin Tendon?
- AAttaches the muscle to the movable bone, so that on contraction the insertion is brought closer to the origin.
- BAttaches the muscle to the least movable bone.
25What does a Ligament do?
- AAttaches the muscles to the bones.
- BHolds bones together.
