how many skeletal muscles are there in the human body? - ANSWER--600
individual muscles. making up about 23% of a woman's body weight and 40% of a
man's. it is the most abundant tissue in the body
what are muscle cells made of? - ANSWER--water 73%, well organized set of
proteins 24%, a limited amount of inorganic salts.
what are muscle fibres? - ANSWER--elongated rod shaped cells making up each
muscle (thousands in one muscle). they are grouped into bundles of 10-150 fibres.
what is fascicle? - ANSWER--bundle of 10-150 muscle fibres
what is the perimysium? - ANSWER--connective tissue that surrounds fascicles.
what is the epimysium? - ANSWER--connective tissue that surrounds the entire
muscle
what is the tendon? - ANSWER--layers of connective tissue that amalgamate at the
ends of the muscle and attach to the bone.
What is the sarcolemma? - ANSWER--a thin elastic membrane that encloses the
contents of one muscle fibre.
What is the endomysium? - ANSWER--a thin layer of connective tissue that
surrounds each muscle fibre

What are myofibrils? - ANSWER--the thinner fibres that comprise each muscle
fibre
What are sarcomeres? - ANSWER--the basic unit of muscle contraction. each one
comprised of two types of protein: a thin filament called actin and a thick one
called myosin.
How does a muscle contract? - ANSWER--the individual myofilament protein
strands within the myofibrils are organized longitudinally along the length of the
muscle cell and interact to allow contraction.
what must happen for a muscle to shorten? - ANSWER--its cells must covert
energy (ATP) into mechanical work (contraction).
the term used to describe contraction in which the muscle shortens - ANSWER--
concentric contraction
the term used to describe a force exerted on the muscle as it lengthens - ANSWER-
-eccentric contraction
Two parts of the nervous system - ANSWER--central nervous system and
peripheral nervous system
what are neurons? - ANSWER--they are nerve cells that that transport nerve
signals through out the body. there are two kinds: sensory and motor.

carry information and sensations from the body and environment to the CNS -
ANSWER--sensory neurons
carry information from the CNS to the muscles to create a response or movement. -
ANSWER--motor neurons
what is a motor unit? - ANSWER--a single neuron together with the muscle fibres
it commands.
Proprioceptors - ANSWER--Sensory receptors, located in the muscles, joints and
tendons that provide information to the CNS to perform coordinated movement
and maintain muscle tone.
What are muscle spindles? - ANSWER--a type of proprioceptor that consists of
several modified muscle enclosed in a blanket of connective tissue. they provide
information about the length of a muscle fibre and the rate of change in it's length.
they tell a muscle how much it needs to contract to overcome a given stretch.
What are golgi tendon organs? - ANSWER--proprioceptors located in tendons near
the myotendinous junction
what are two muscle fibre types? - ANSWER--slow twitch and fast twitch
muscle fibres best suited for endurance work due to their ability to use oxygen and
resist fatigue - ANSWER--slow twitch fibres: contain more mitochondria, contract
slowly and produce a lower amount of force but are more resistant to fatigue. work
aerobically.
