DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A
What are sarcomeres? – \u2026.ANSWER\u2026the 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? – \u2026.ANSWER\u2026the 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? – \u2026.ANSWER\u2026its cells must covert energy
(ATP) into mechanical work (contraction).
Two parts of the nervous system – \u2026.ANSWER\u2026central nervous system and peripheral
nervous system
what are neurons? – \u2026.ANSWER\u2026they 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 –
\u2026.ANSWER\u2026sensory neurons
carry information from the CNS to the muscles to create a response or movement. –
\u2026.ANSWER\u2026motor neurons
what is a motor unit? – \u2026.ANSWER\u2026a single neuron together with the muscle fibres it
commands.
Proprioceptors – \u2026.ANSWER\u2026Sensory 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? – \u2026.ANSWER\u2026a 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.<\/p>\n\n\n\n
What are golgi tendon organs? – \u2026.ANSWER\u2026proprioceptors located in tendons near
the myotendinous junction
what are two muscle fibre types? – \u2026.ANSWER\u2026slow twitch and fast twitch
muscle fibres best suited for endurance work due to their ability to use oxygen and
resist fatigue – \u2026.ANSWER\u2026slow twitch fibres: contain more mitochondria, contract
slowly and produce a lower amount of force but are more resistant to fatigue. work
aerobically.
muscle fibres best suited for short intense bursts of activity – \u2026.ANSWER\u2026fast twitch
fibres: able to produce and use atp more quickly, contract quickly and produce a lot of
force but fatigue quickly, work anaerobically.
what affects the percentage of each fibre type in a muscle? – \u2026.ANSWER\u2026the function
of the muscle, training and genetics.
which fibre type gets recruited first during exercise? – \u2026.ANSWER\u2026slow twitch
most of the gains in muscle in the first weeks are due to – \u2026.ANSWER\u2026neuromuscular
adaptation – as the brain learns how to tell the muscles to generate more force
factors that affect the ability of a muscle to generate force – \u2026.ANSWER\u2026muscle size,
length, speed of contraction, neural control
the attachment of the muscle tendon to the stationary bone is – \u2026.ANSWER\u2026the
muscle’s origin
the attachment of the muscle tendon to the moving bone is – \u2026.ANSWER\u2026the muscle’s
insertion
rectus abdominis antagonist – \u2026.ANSWER\u2026erector spinae
biceps brachii antagonist – \u2026.ANSWER\u2026triceps brachii
quadriceps antagonist – \u2026.ANSWER\u2026Hamstrings
anterior tibialis antagonist – \u2026.ANSWER\u2026gastrocnemius and soleus
shoulder girdle bones – \u2026.ANSWER\u2026clavicle and scapula, it connects the upper limbs
to the axial skeleton. the shoulder girdle is considered to be a group of floating bones
since they are secured only by muscles. it is an unstable area but has a large ROM
Rotator Cuff Muscles (SITS) – \u2026.ANSWER\u2026Supraspinatus, infraspinatus, teres minor,
subscapularis.<\/p>\n","protected":false},"excerpt":{"rendered":"
