Q

Explain muscle composition.

A

Each muscle is composed of many cells held together by connective tissue. Each muscle fiber receives its own nerve impulses, triggering various motions. That signal or impulse then travels down the nerve to the muscle, then the muscles fibwe changes chemical energy into mechanical energy

Q

What is the difference between voluntary and involuntary muscle control

A

Voluntary muscles can be controlled by thought wheras involuntary muscles are those that are automatically controlled by the nervous system and cannot be moved at will

Q

What is the primary function of the integumentary system? What part(s) of the body are considered integument?

A
23
Q

What are the three layers of skin?

A

Epidermis
dermis
hypodermis

24
Q

Compare and contrast Sarcoptic and Demodectic Mange

A
25
Q

Describe the steps to safely cutting dog or cat nails

A
26
Q

Identify the types of muscles that are voluntary. Identify the types of muscles that are involuntary.

A

Skeletal muscles are voluntary whereas smooth and cardiac muscles are involuntary

27
Q

What is the nervous system?

A

A control system that acts largely unconsiously and regulates bodily function such as the heart rate, digestion, respiratory rate, pupillary response, urination, sexual arousal

28
Q

Explain the skeletal muscle

A
29
Q

Where are skeletal muslces located?

A

Head and neck
Muscles of respiration
abdominal
thoracic limb
pelvic limb
cutaneous

30
Q

Explain the cardiac muscles

A
31
Q

Explain what smooth muscle is

A
32
Q

What are the two types of smooth muscle an examples of where to find them?

A

Viseral smooth (in sheets of cells found in the walls of hollow organs)
bladder, intestine, uterus
Multi-unit smooth (small discrete groups of cells that work on their own)
muscles in the eye, respiratory tract, small blood vessels

33
Q

What are the two types of connective tissue?

A

Fat and fascia

34
Q

What are the muscle attachment sites? Which is more stable?

A

Origin and insertion
Origin is more stable because it doesnt move much when the muscle contacts

35
Q

Tendons attach _________ to __________
Ligaments attach ___________ to ____________

A

Tendons attach muscle to bone
ligaments attach bone to bone

36
Q

List the four Muscle actions.

A

Agonist - the prime mover
Antagonist - directly opposes the action of an agonist
synergist - contracts at same time as the agonist to assist its actions
Fixator - stabalizes the joints to allow other movements

37
Q

Identify the primary functions of the integumentary system

A

protection of teh body
houses sensory receptors
regulates body temperature
produced vitamin d
secretes and excretes substances through the glands of the skin

38
Q

Identify the layers of the integument

A

Epidermis
dermis
hypodermis

39
Q

What are the four cells of the epidermis?

A

Karatinocyte
gives skin reciliency and strength
Melanocyte
produces melanin pigment
langerhans cell
merkel cell

40
Q

identify and describe the special feautures of the integument

A

Pigmentation
the result of the presence or absence of melanin granules in extensions of melanocytes. Controlled by hypophysis
Paw pads
tough, thick layers of fat and connective tissue. contains all 5 epidemal layer. They are pigmented with multiple foot pads (carpal, metacarput and metatarsal pads and digit pads)
Planum Nasale
top of the nose in cats, sheep, pigs and dogs. It is usually pigmented with three epidermal layers
Ergots and chestnuts
dark, horny stuctures on legs of equine family that are thought to be vestiges of digits. chestnuts are located on the inside of each leg at carpus and tarsus while ergots are buried in caudal hairs of fetlock
Cutaneous pouches in sheep
infolding of skin that contain fine hair and sebacecous and oil glands. located in three locations (the infraorbital, interdigital, and inguinal)

41
Q

Identify the related structures of the integument

A
42
Q

What is the stratum corneum?

A

The outermost portion of the epidermis. It accounts for 75% of total skin thickness. It is relatively waterproof and prevents most bacteria, viruses and otehr foreign substances from entering the body

43
Q

Dermis gives the skin its _____ and ________

A

flexibility and strength

44
Q

Where are the sweat glands located and what else is located there?

A

the dermis. it also contains nerve endings, oil glands, hair follicles, and blood vessels

45
Q

What are the two layers of the dermis?

A

Papillary
thin layer below teh epidermis loops bloods vessels and nerve endings
Reticular layer
80% of the dermis

46
Q

What is the function of the hypodermis?

A

It allows skin to move freely over underlying structures
contains blood and lymph vessels, nerves and fat tissue
where pain receptors are
