What muscle pulls the chin toward the chest?
Sternocleidomastoids flex the head toward the chest when acting together but alone, one sides bends neck toward shoulder and turns face to opposite side.
Which vessels carry blood back toward the heart?
Veins carry blood back toward the heart. They have valves to prevent backflow and rely on muscle contractions and breathing to help push blood back to the heart.
What is the process that propagates nerve impulses toward another neuron muscle fiber or gland cell?
The process that propagates nerve impulses toward another neuron, muscle fiber, or gland cell is known as synaptic transmission. When an action potential reaches the axon terminal of a neuron, it triggers the release of neurotransmitters from synaptic vesicles into the synaptic cleft. These neurotransmitters bind to receptors on the postsynaptic cell, leading to the generation of a new action potential in the case of another neuron or muscle contraction in the case of muscle fibers. This process ensures the rapid and effective communication between cells in the nervous system and across neuromuscular junctions.
Where is the gracilis loacted?
The gracilis muscle is located in the inner thigh of the leg. It is a long, slender muscle that runs from the pelvis to the shinbone, helping with hip adduction (moving the leg toward the midline of the body) and flexion of the knee.
What is a shift in the electrical potential across a plasma membrane toward 0mv?
A shift in the electrical potential across a plasma membrane toward 0mV is called depolarization. This occurs when the inside of the cell becomes less negative, potentially triggering an action potential in excitable cells like neurons and muscle cells.
What will the other muscle do while the thumb is pulled toward the finger?
When one muscle contracts, the other one expands.
The first step toward generating a skeletal muscle contraction is The first step toward generating a skeletal muscle contraction is?
stimulation of the muscle by a nerve ending.
What muscle do you use to bend your forearm toward your shoulder?
Triceps Muscle
What brings a bone toward a longitudinal axis?
Medial rotation is movement toward the body midline.The arm at the shoulder:Deltoid muscleSubscapularisTeres majorLatissimus dorsiPectoralis majorThe leg at the hip:Tensor fasciae lataeGluteus mediusGluteus minimusLeg at the knee:PopliteusSemimembranosusSemitendinosusThe eye (Incyclotorsion):Superior rectus muscleSuperior oblique muscle
Babies born with congenital torticollis are unable to rotate their heads properly and their necks are twisted to one side. The muscle that is affected in congenital torticollis is the muscle.?
Congenital torticollis occurs when the neck muscle that runs up and toward the back of the baby's neck (sternocleidomastoid muscle) is shortened. This brings your baby's head down and to one side. This is known as congenital muscular torticollis
What is the most common fingerprint?
The most common fingerprint pattern is the loop, which occurs in about 65-70% of the population. Within the loop pattern, there are ulnar loops (looping toward the little finger) and radial loops (looping toward the thumb).
The North Atlantic what brings warm water toward Europe?
A drift
What are the muscles called that brings a body part toward the body?
Adductors
The first step toward generating a skeletal muscle contraction?
stimulation of the muscle by a nerve ending.
Which type of movement bends the knee and brings the lower leg toward the back?
flexion of the knee.
During muscle contraction the moves toward the?
During muscle contraction, the Z-lines move closer together as the sarcomeres shorten. This is due to the sliding of actin and myosin filaments past each other, resulting in the contraction of the muscle.
What abdominal wall muscle pulls thoracic cage toward pelvis?
Rectus abdominus
